"I couldn't Juggle to save myself" she said, I whispered under my breath "if you had to save yourself, you would learn how to juggle pretty quick".
If you had to change, to save yourself, you would probably do that pretty quick too.
Now juggling offers you quite a safe way to learn something new, you think is reasonably difficult, however as you'll find it's quite easy with the right help.
What I'm saying is if you use juggling to learn the principles of doing something new, then learning to juggle three balls gives you the confidence to do whatever you would like to do.
