I feel like that was in part, I got much better at the skill of noticing things and thinking harder about predicting things. Also, there is just a thing where after a while every idea feeds on itself and builds on itself, you like to pick up a whole collection of useful ideas which you can apply to everything. I love… Gian-Carlo Rota has a good quote for how he does research where he said like, “Everyone has two mental tools that they apply to every problem, and a great mathematician will have 3.”
