This is the important part. You _have_ to keep learning. I work with a coworker who's in his 50's, he's flippin' GREAT. Super dependable, takes responsibility, likes to come in an hour early, code, not really talk to anyone and go home at 4. You can give him any project and he'll get it done, with tests and documentation and a one command deploy script. If I ever started a company I'd hire him in a heart beat. I worked with a "grizzled veteran" at a previous job... He was difficult. Kept talking about how he had a "classical" computer science education background from Stanford. Over complicated everything. Never took responsibility. Never wanted to learn anything new. Just a pain, we ended up working around him whenever possible. So if you really like doing what you're doing great! I'm actually going the opposite route now. I'm 29 and actively trying to hop to sales because I know I don't want to spend that much time coding anymore. Different strokes for different folks. There's engineers at google making 300k and sales people making 80k and vice versa.
