20 years ago, my grandfather kept telling me that if I wanted to "get into computers" I should get a job as a cleaner, because if I worked hard as a cleaner the boss would notice me and promote me.
Didn't listen when I told him that cleaning was all contracted out and the "boss" would never see me working hard as a cleaner.
Same holds for famous artists: talk to their parents and they probably say that he/she was always singing with a fake microphone in front of a mirror. 90% of the kids do that...
