Advice
Manage your time well, and don't be afraid to ask questions that you think are unimportant. No question, no matter how small, is inferior to another when it comes to research development or your own, coherent, understanding of an issue. I can tell you that regretting to ask a question that impedes the process of your research is a lot worse than confronting the fear of what response you may receive in the first place. Understanding this will help you develop more of a tenacious attitude in whatever work experience you will have in the future; and in turn, will help you further your career and your life.
