    I'm 31. Here are 10 tips I wish I told me at 21. 1. You have zero talent. You will think you are "good at things," but you are not. Anyone can GET good at anything, but you have to work hard to get there. Others will be better than you at the start. That's ok.

    I am working on the ultimate, best, most complete full stack web3 free learning course the world has ever seen. Everything is filmed. I am just editing all the pieces together now. Delivery date all depends on how fast I can edit.

    We had a candidate reach the coding portion of our interview process. The task: โ€œBuild an X, use whatever tools you want, just share your screen and thinking aloudโ€ 90% of it was him asking questions to Claude. We hired him. He asked Claude the best questions.
