Well, I'm not and no one should be "coping" (with being in their 30's!), and it's not a "decline". It's only a decline if you look at the downside and not the upside.

I totally agree that you have more raw energy and there is more potential for excitement when you're 14. But like I said, if you want to write good software, "energy" and "excitement" are not top on the list of attributes you need.

I think the OP is basically describing mild depression, which is a completely different issue, unrelated to getting older. You can be depressed and young or depressed and old. In fact I was a lot more depressed when I was younger.

You turned an issue of motivation into an issue of age, when they're not the same thing.

Perhaps if your goal is to write the next Facebook, and you're in your 30's, the time has passed. You're not going to be Zuckerberg, or Larry Page. I guess some people have trouble coming to grips with that. But personally I don't care so much about those kinds of things (and didn't when I was younger either.) You're not going to be Van Halen or Jack White either. Suck it up :)
