If you are 13, then it is better to concentrate on your school studies. You study should not make you spend 10+ hours on your laptop. You can work on your laptop during holidays.
Hahah yeah for kids this day. Is true school is the most important to be successful in life not only in school, but good with social life and other stuff school is just 25% of it. Well when that 13 years old kid is watching some movies I think doing some faucets is good or posting you can earn a lot of money with just doing that.
