I can't write code nearly as fast as I used to. I am much better at writing less code, though. And though it took a while (too long), I've figured out that it's the code you don't write that makes you great. So I'm much more skilled and competent as a 40 yo than I was as a precocious 20 year old. The biggest change has been values though. My values and my criteria for success are different now than they were when I founded my first business at 22. Now with a family, assets, residual income and a home, I'm far far more interested in being interested than I am in numerical 'success', and much more motivated by social justice. So I definitely don't have the hunger for startup life. I don't feel lost in that culture. I just feel that I've been there, got the t-shirt, and moved beyond, so I don't feel the need to go back for more than the odd visit. So yeah, maybe I'm getting over the hill in some ways. But that's not a bad thing. I don't feel out-competed, I just feel like experience and perspective have made me change what I value, both in code and in business (and other bits of life: in relationships, in vacations, in hobbies, etc).
