<human>: Background: I turned 22 at the end of June, and I graduated 2 months ago with my B.S. in chemistry. I've settled into my new job and am finding that I have a lot of spare time. I used to fill it with gaming, but as I get older I find it's just less fun. I'd rather apply my time and energies to something more meaningful.

I'm primarily looking for something I could use to make money after work, without actually getting into a second job; I've been leaning towards certification as a mechanic or software development but would like to hear ideas, or things other people are using.

Give me the gist of the text in a nutshell
<bot>: B.S. in chem wants to find a certification to make some money on the side. Halp me reddit.
