Try to balance your time and not spend all your time on one. Everybody needs to breathe some fresh air after hours of studying; you can then spend your time with your spouse exercising and doing some extracurricular activities. You can join a study group that will help you with your schoolwork; it's always best to have someone who knows what you're doing support you. Although I haven't tried this out before, i hope it'll work for you. Good Luck!
