I just found a great post by Sam Altman where he writes about Productivity. There are lots of gems in there but I really enjoyed these two thoughts:
The most impressive people I know have strong beliefs about the world, which is rare in the general population. If you find yourself always agreeing with whomever you last spoke with, that’s bad. You will of course be wrong sometimes, but develop the confidence to stick with your convictions. It will let you be courageous when you’re right about something important that most people don’t see.
Try to be around smart, productive, happy, and positive people that don’t belittle your ambitions
