which online skill that can earn me $1000 in a few months?

I’m looking for an online skill that can earn me $1000 in a few months. I’m 19 and in college. I don’t have any skills, just a good laptop and internet. I can dedicate about 4 hours a day to learning because I’m working. If I start working in that skill, I can work even more; I have no problem with that.
