I've been in the tech industry my entire adult life. My grandpa taught me to program when I was six years old (QuickBASIC!). I'm self-employed and do well for myself. I've worked remotely my entire life and have never had a month where I didn't have paid work.

But month after month, I continue to have this feeling that I'm not good enough. That the industry will inevitably leave me behind and that I'm doomed to eat dog food out of a can in my old age or something.

I'm 31 now, so I definitely have a slightly less euphoric view of the working world than I did when I was 21. I'm more experienced and less willing to take work I know won't be a good fit. But I also feel, well, "old".

How many of you suffer the same delusions? What do you do to cope?
