Forget trying to work out if you have any 'natural' ability (though since programming is a man made invention you can work out if you have any natural ability in the field by testing your problem solving abilities).

Get going with it. Find an open source project that interests you and contribute. There are a few things that are bad about github but as a platform it really allows you to find issues in software you're interested in, fix it and then submit that fix.

If you work for someone that's ideally the situation you're in, you're working on a software problem that interests you implementing new features or fixing bugs and submitting them.
