I try not to put too much stock in the endless hole of people talking about Silicon Valley and startups and the tech world on the internet. But this quote caught my eye:
You need to know the things that you need to know to solve the problem. And you need to not believe things that will get in the way of solving the problem.
Sourced here, which credits the quote to Scott Klemmer, though I can’t find the original anywhere. He was talking about design and what research says about creativity, but I think it applies well to problem solving in math. Leads me to the question: is there anything else to problem solving?
