I'm a 38yo male and was (in my high school at least) some math prodigy. But hormones got in the way, I wasn't a great student at university and decided to study economics. I have a pretty good job at a well-known software company but it still itches to do something with my talent. My dream right now is to become a Math professor. I'm really considering starting a Math degree at my local university and see where it takes me. If I'm just mediocre or even bad, or don't enjoy it, I'll stop pursuing it, but if I'm great than I really hope to get a kick out of it and just keep going. I've kept my Math skills a bit up to date, so I won't have to overcome a 20 year pause. I've got some cash to keep me going for a couple of years, but would need a plan to generate money in meanwhile, that's what's holding me back somewhat at the moment.
