10 years doesn't necessarily mean all that much. You might have only 3-4 years of experience, but if it's good experience, it'll beat the pants off 10 years of crap experience. Not saying anything about dshipper's situation, just in general length of time doing something doesn't necessarily make you that much better.

I say this as someone who's been working with software for 30 years, professionally for 17 years. I've gotten a lot better over the 17 years, thanks to many of the experiences and time I spent learning things. I've also been playing guitar for over 20 years, and am still pretty lousy at that. :)

Don't be too depressed. I've been programming in some measure since I was ~4, and I'm 23 now. Many of those years were me slowly teaching myself, because I had no mentors.

It's really not about time, it's about projects and people. You learn by doing, not by time spent. Don't worry about it.

Don't be. Coding at age 10/5/2/whatever is usually copying straight off books, and/or devising the most simple and crude software. It's no indicator of future ability, and frankly it usually is mentioned as a form of adolescent chest thumbing.

Just keep programming, you'll catch up in no time.
