I can completely relate to your situation as I have also gone through the same experiences where you have to make a decision as to which option will work the best for you. My suggestion to you is, make a decision with both head and heart.If I were you I would prioritize my studies as the number one option because if you are well educated that would be a path towards a prosperous life where you will have the ability to provide for your family, that's a logical decision you take using your head. Its not possible to study all day and all night long, and there is a saying that goes "All work and no play makes Jack a dull boy", so find your passion, something that you love doing from your heart, it can be taking up sports,learning to Dance,photography,debating etc.Its not possible to do everything in life at once but its possible to do it one after the other. If you are devoting 4 hours to study everyday, make sure you devote at least 1 hour during the day to pursue what you enjoy doing the most or take a break on every Saturday and go hiking or biking or whatever pleases you.If one Saturday you go on a camping trip then plan the next Saturday to go to the beach and play volleyball. Its all about integrating everything in life and prioritizing to keep on working on something which is very important to you which I guess at this moment is education.I hope this helps.!
