Advice
One piece of advice I would offer is that if you ever are given a task and it is taking you an incredibly long time to do it or understand it, don't be afraid to ask for help. It is likely that there is some simple short-cut that you just aren't aware of. While you should do your best to be resourceful on your own, do not miss out on the opportunity to pick the minds of your mentors and gain insightful knowledge about the field or even simple tasks.
