When you give a class report, make eye contact around the room. Avoid running over by practicing ahead of time. Reading is less effective than is talking from notes. Look for study groups to join. If you can't find one that will help you, form one.
Praise is more memorable than complaining.
Praise other students who have good ideas, good teaching when you find it, good books that you've read. You will never receive anything you haven't requested. That includes fellowships, extra help, and publications. Sometimes the answer to your request will be no. A negative answer is no reason to quit asking.
