Programming

So, I will start by saying "Yes, you can do it. It's not too late and programming is fun and fulfilling".

However! One thing my experience has taught me in seeing people approach and bounce off programming is: programming is a fail-til-you-get-it type of endeavour. Your first several years will be littered with broken code, because there are a thousand little things you have to bump up against before you unlock one more puzzle piece.

So! If you go for it, persevere! You aren't a bad programmer, or a slow learner, because you can't get your code to work. Every single one of us ran into the same issue, and we just had to push through, learn to Google, and try again until it sorta-kinda works. You in 10 years will be embarrassed by what you write in your first years

Luck should be taken into account. Once you are done with your degree, perhaps the market will have recovered a bit, because I'm hearing a lot of negative feedback lately.

edit: If you're not sure, you can take a peek at this graph of free MIT YouTube courses. Choose something interesting on the right, then figure out where to start on the left to get to your chosen point. Each course can easily take about 100 hours, which sounds a lot, but if you do them you can take that knowledge and more easily extrapolate information in the future.
