I'm a similar age to you & quit a programming job/career in my 20s 

I had the Bach degree & the job but I left it to pursue something more suited to my skillset & abilities. I was a slow programmer & had a very fixed mindset at the time. With hindsight I could have pursued it, worked hard & succeeded, but my heart wasn't in it.

It's a very competitive industry that's constantly changing & evolving.

I've no regrets except the wasted University time & money.
