How to learn to play tennis
It made me
Sad 
"I had a horrible instructor."
How I did it: The only reason I didn't really enjoy learning to play tennis is because I had a really awful instructor who couldn't care less about my progression. He just sort of made everyone feel bad about themselves. Unless you were a natural, he didn't really bother with you. So for that reason, I absolutely hated learning tennis. He pretty much ruined it for me.
