You don’t always know when you’re going to get burned. Most of the time you were not trying to get burned, it just happened. Sure you learned not to touch the stovetop when it was on early, but then there was that volcanic microwave burrito you put in your mouth. As we get older we are more and more careful of dangers, but at some point fear of taking action can slow our response time into inaction and kill the growth our initiatives need. Knowing when to act is more about recognizing the urgency and the importance and being prepared to act when the risk is justified.
