Do you ever regret not living up to your potential?

This could be long so grab a cuppa. I just joined today and I have a question. Does anyone else really miss the them that could have been? For context, I was the 'gifted kid', tipped for doing maths at uni, did the tournament chess circuit, won library prizes etc... and for all that, I have spent nearly half my life on disability, in the last few years my medication combo has started working well enough that I can work but grateful as I am for that, for all that promise I had, I'm a part timer at an unskilled min wage job. Part of me wishes I could see the way my life could have gone, part of me doesn't want to know because it would be too depressing, but sometimes I wish I could have gone the productive route with my life.
