I started when I was around 11, I didn't get really serious though. It was with Basic. Then a bit of c in high school and then nothing until much later in life. Probably on and off with frontend web stuff from my early to mid twenties, only about age 30 did I get serious about it and started learning Go.
I wouldn't say I regret not starting sooner, but there are times I wonder how far I would have come if I had.
