Anxious? Dealing with Stress as a Founder

Working with a couple of founders I noticed that none of them are equipped to deal with stress. They just bottle it up and sooner or later it just blows into their faces. From procrastination to panic attacks, i've seen it all. Of course, meditation and other exercises can work but when you're in the middle of an anxiety attack you don't start a gratefulness journal. I started to publish weekly a short exercise to help ease the stress. Basically building an emotional first aid kit that one can use anywhere, anytime without any preparation in advance.

To make this better, I need your help: how does stress affect you and how do you deal with it?
