As a young man away from home for the first time, I experienced these difficulties:
Whether it's roommates, classmates, advisors, professors or teaching assistants it was necessary to communicate well. Avoid making assumptions and instead communicate directly and honestly.
- Time Management
For the first time in my life, I was free to set whatever schedule I wanted. I often greatly underestimated how much time I would need to complete class assignments. I procrastinated, putting off working on assignments whose due date was "far" in the future. The best advice I can give you is keep a calendar of all your assignments and make daily incremental progress on long term projects and complete short term assignments as quickly and as well as you can.
You can't do your best work if you are sick or just feel bad. Wash your hands, exercise as often as you can, eat well and give yourself time to sleep. Sleep is often difficult with roommates, respect their sleep time and ask them to respect yours.
Enjoy yourself, the college experience is whatever you make of it. Meet different people, learn what things excite you, do them now instead of waiting for your "professional" life. Ask questions and seek help whenever you feel stuck.
