Graduate school especially is all about deciding on projects and following through with them. Plan your time wisely. Don't plan on working 40 hours and go to school if you've never done it before. Realize you need time for homework and reading, two things you probably weren't budgeting for during the summer. Finally, remember to take time for yourself and ask for help if you need it.
Graduate school can be difficult, but it can also be rewarding.
It can be a lot of fun. Inc. All rights reserved.
