When you are in your first year at college, document yourself a little bit and then put up a website / blog. On this occasion you will learn a lot of useful things. You can get in the year 2, 3 or the last of the faculty to make money from that.
If you are really good, you can win after the first 7, 8 months receive money with the help of the site / blog. I have a few friends who make money with this, and a few live with the money they made.

- Money as a student without a job -

Another thing I like is web design and web development.
If you learn this, you will have a great advantage in life. I know very little about the two things, but I learn every day. I'm sorry I did not learn when I needed it, but I have time. After graduating, learning web design and web development, you will definitely find a job, if you do not want to stay at home and work on your own.
