I've tried to pursue a career for the last two years, specifically an exam. I've worked hard but have been faced with barriers each time. I've done istikhara on this 3 times and it has turned out good each time. I did a nadhr that I still need to fulfill parts of, I try to do salat al layl as much as I can, and I make duaa often. I feel stuck, and I ask Allah to open the doors of rizk and fate that he has written for me career wise, but I'm not sure what other things I can do.
