Don't Stress
I'm one of those people who rarely stresses, if I am, then I tend to nip it in the bud, and tackle it straight away.
Sadly a work mate the other day couldn't keep a lid on it, and exploded... I'm glad I was on my break at the time. Due to his actions of worrying about nothing, he fell over. His mind wasn't on the job at hand and that's why I'm glad I take everything in my stride and go with the flow.
