Decisions-Decisions

So when you work full-time (mon -fri 8-5) then go to school Mon Tues and Thurs night (6p-10p) and play in a softball league wednesday nights and soccer league Fri and sat night... when do you find time to do work for your personal business. My classmate/coworker/business partner Zack and I have started getting work offers lately and it sucks because we cant find time to do them in the time frame people need them done in. I dont know if I should give up my sports and do this work and have absolutely no "FUN TIME" for myself.... or just wait till I graduate in May to accept any offers on work. At least then i will have time when i get out of my daytime job to work on it at night because i will no longer have school at night. I feel like if I give up my sports (which are my only relief during the week) right now I may just lose my mind working all the time. Its crunch time though and I need to make a decision, I really dont wanna let these customers go by but then again I dont think it is healthy to be all work no play either.
