I tried to play the piano, but the instructor told me my fingers are too stubby and my manual dexterity was awful, so I would likely never learn to play piano with any skill.
Since I play a numerous instruments, I decided they did not know what they were talking about and I can play anything I want. Besides that, my mom told me I can do anything I set my mind to when I was growing up.
Turns out they did, I can't, and my mom lied.
