Ask HN: What are your thoughts on multiple jobs?

Hello friends,

I am a recent graduate, employed full time at a startup. Since I have not started a family, I do have some spare time on my hands. This is a rare/short opportunity as I believe when I have kids, I would like to give them a lot of my time.

I was wondering what are your thoughts about doing contract/part-time work during the week in evenings?

Would I simply burn myself out?

My goal here, other than having more income, is to learn as much as I can. I believe the best way for me to do this would be to work on "real world" projects.

Note: I am a person that prefers full transparency so, if I end up doing something like this... I would have made all parties aware of the situation.
