What’s so weird about dreading things that might happen is that you have usually already figured out what you’re going to do if it does. In which case, your role in the whole situation is kind of over.
Why the anxiety? Do you doubt your ability to stick with your own plan? Ok, so focus on that. Do you think the universe registers your fears and then takes them under consideration? No, obviously not. So you want to feel miserable for fun then?
