There isn't any specific advice in the Qur'an and hadith about this, apart from the general advice that it is good to have a profession.
However, you could consider what types of things you enjoy doing and come easily to you, and also what skill sets are easiest for you. (For instance, are you good at working with your hands, art, people skills, mathematical skills, etc.)
It is also good to ask other people for their advice since they may see things in you that you are not paying attention to.
If you have the opportunity, you can also try different things and see what does or does not suit you. Every master chef begins with the first dish! The difference between the master chef, and the person who quits and does something else, is that the master chef perseveres.
Sometimes people do multiple things in life (at the same time or at different times), so you do not always have to choose one thing.
Also, people are often quite successful in jobs or endeavors that are not really their "true passion" or their best talent but are simply something they began to do or had to do. Possibly this is because when something does not come naturally to us, we have to work harder to get good at it, and, in the end, someone who works hard to learn a skill will do better than someone who has natural talent but who does not work to develop it. Most people can do most things with training and effort.
You can also consider what is important to you, how you would want to be remembered after your life, or if there is any particular group you want to serve. For instance, some people go into Islamic religious work because they want to serve the ummah, or feel a similar calling. Some people go into medicine because they want to help people or see a need for it. Some people go into business because they admire people who are successful at business or want to provide a certain product or service somewhere, or help a certain community economically.
With duas for your success!
Yes it is very good to pray for the guidance and forgiveness of your parents.
It is also allowed to pray for deceased Muslim for forgiveness and mercy from Allah (SWT).
You can visit some useful websites like Al-Islam.org or rafed.net or Shia search.org and read about the principles of faith (Isool Al-Deen) then read about the practical rules e.g Prayers, fasting, Hajj, Khums etc.
If you have any question, you are welcome to ask on this website.
Mut'ah marriage is a type of marriage in Islam. It has been mentioned in Quran (Sura 4, Verse 24). Your confusion might be because of misinformation. You can read about this Islamic marriage on many websites including www.al-Islam.org.
The Prophet Muhammad (SAWA) taught the Muslim this type of marriage to save themselves from sinful sexual acts. It was practiced by Muslims during the time of the Prophet (SAWA) and government of Abu Bakr and part of the time of Umar, who banned it admitting that it was allowed by the Prophet himself. Hundreds of Hadeeths mentioned Mut'ah marriage in Shia and Sunni books including Bukhari and Muslim books of Hadeeth.
Mut'ah marriage is similar to permanent marriage in many conditions with few differences. Mut'ah marriage has a Mahr like permanent marriage and can never be allowed with an existing married woman just like permanent marriage.
Mut'ah marriage has a fixed agreed time and it does end by the end of the agreed time. No inheritance between them in Mut'ah marriage nor financial liability of livelihood unless agreed in the agreement of the marriage.
The children from Mut'ah marriage have all the rights of children from permanent marriage.
Waiting period after Mut'ah marriage is two menstrual periods.
Muslim woman is not allowed to marry non Muslim man under any circumstance until and unless he becomes a Muslim.
We are allowed to pray to Allah for non Muslim to be guided and to see and follow the true religion of Islam.
Thank you for your question. The general principle in calling towards good and forbidding evil is that it is only applicable if you are sure someone will listen to you. So your duty is dependent on that assessment.
Usually, there is no need to proactively try and convert classmates, but perhaps with your good conduct a person may ask you some questions about your religion and at that point, you may consider the best way to guide them.

This can happen in few incidents when you find what you think as an answer in the Quranic verses, but it can not be taken fore granted in every case. You need to understand the meaning of the Quranic verses. You might need some times to seek advice from reliable Islamic scholars.
Allah (SWT) guided all human beings to the right and warned them from wrong. (We showed him (human being) the two ways,; good and bad) (Sura 90, Verse 10).
(Verily, We showed him the way, (for him to decide) whether to be grateful or ungrateful) Sura 76, Verse 3).
Allah (SWT) helps every one who wants to be guided, as He kept the instinct knowledge in every human being about the main facts of the existence (Tawheed, Adl, Nubawwat, Imamat, and Qiyamat) and helps those who want to strive to be guided (Those who strive in Our way, We will verily guide the to Our ways ) (Sura 29, Verse 21). But those who refuse the guidance of Allah (SWT) and insist on refusing it, will be let alone with their own option.
Allah (SWT) is gracious to all His creatures and He showers His Mercy on all of them : My Mercy included every thing .(Sura 7, Verse 156).
Guidance from Allah is always offered to every one who wants it, but it can not be enforced on those who insisting on refusing it.
Thank you for your question. The purport of the verse is that the result of struggle and strife in the way of Allah, be that military, against satan or against the lower self, is an increase in guidance on the pathways that lead to God.

It is the responsibility of every Muslim to guide others to the right path as much as possible and whenever there is a possibility of positive effect. If you feel that the unbeliever can listen or think and will not re act in a diverse way, then you should approach him with wisdom and good way as Allah ( SWT) says in Quran ( Invite to the Way of your Lord with wisdom and good preaching and discuss with in the best way) Sura 16, Verse 125.
inviting people to the True Faith is not an option but a necessity otherwise how people can be guided if the believers don't invite them.
Being negative and not doing any thing to invite unbelievers when there is a possibility of effect, is not accepted from a believer who understands his duty towards Islam.
There are many Hadeeths emphasizing on the importance of inviting people to the True Faith, stating that inviting to Islam brings the reward of a prophet to the person who invites one unbeliever if his invitation was not accepted, but if the invitation was accepted, the reward will be like the reward of all the prophets.
The believer who invites others to Islam with wisdom and good way, is following the practice of the prophets, that is why, he gets the reward of a prophet.
Thank you for your question. This is an issue of wisdom and the "right" answer varies according to the situation. Inviting people to Islam is also done in different ways and so a certain amount of tact is required. However, there is no harm in speaking about Islam when you think the opportunity presents itself. And while Allah (swt) is the one who ultimately guides He does that more often through means.
May you always be successful
