Defense Mechanisms!

I will NOT get sick! Not only does this potential cold I am NOT getting put a damper on my outdoor running plans, but it really ruins my singing.
I've got a huge amount of rehearsals and performances scheduled for the next week and a half, and I have NO TIME for this sore throat and runny nose.

You hear me, germs!?!?!?

Here are my defense mechanisms. They've worked for me all winter. My optimism says they will work now, too.

What works for you?
