“What lies in our power to do, also lies in our power not to do.” -Aristotle.
The worst thing that can happen to you is nothing. When you make the decision not to do something that might even change your life, what happens? Nothing. And this sum of “non events” takes you nowhere. Think about this and remember all the decisions that were not made and all the actions you did not take and where they could have led you. Now think about all the decisions you made and actions you took and how much they changed your life.
Was the result always positive? Because the worst thing that can happen to you is to do nothing.
