I'm 17. I have school 5 days a week. I work on weekends on a café for 5 up to 10 hours per day.
I take 4€/hour. So, if I work just a Sunday for 6 hours it's almost 25€/week.
Recently, I started trying online methods to make some cash. Well, currently I earn almost the same money or even more, with my real job. Why not then? (:
