I guess we could also consider and take a look on going to college.
There are people who went to college and at the same could also do business, could travel, could also be a volunteer, could read, read, read and could also create things.
While learning on different subjects, students could also do other stuffs.
When the right perfect time comes when a student could see his/her potential on a certain thing, he/she could develop it and eventually focused on it and slowly manage to do on his own. This is what happen to Bill Gates and many others who drop college and pursue the things they're expert in.
