How to choose a career?

[Infinity]

You have to choose something you love. Something that's going to make you treat it everyday like it's your first day.
If you are not going to love what you do then you will just basically be miserable.

^ This. I've seen people pick a career based on how much they were paid and they were completely miserable. If it isn't something that you love to do, you're going to dread going in to work on a daily basis. If it's something you love then that's what you should go for. I had a hard time trying to pick exactly what I was going to school for, so I just combined two of my favorite things (kids and medicine). So think about things that you like, and pick the thing that you like the most. Or combine them like I did.
