I did actually try out quite a few things before settling on infosec.

Like you I programmed as a kid, but did a degree in music (could not get work though), moved back to IT and programming (could actually earn money!). But after a while decided I didn't want to do that either. Moved to info sec in my 30s.

So it is possible to change careers later on. By that time though I had already figured out I needed to earn enough money and I had IT and software skills and experience. Moving to info sec was more of a lateral move I guess.
