I Cannot Blow A Bubble With Bubblegum

I think we all have one of those simple tasks that everyone else seems to be able to do but we can't.

For me, I cannot blow a bubble with gum to save my life.  I have tried and tried but still, I can't do it.  I have friends who can't shuffle a deck of cards and I can do that no problem.  I guess it's a trade off, but I want to be able to blow bubbles.

What's a simple task others can do but you can't?
