The secret of doing “new little things”: Overcome fear by summoning your Courage
I remember many years ago the Cartoon Network channel had a cartoon series named Courage The Cowardly Dog. This was a cute series about an excited and frightened pink dog that had been living in a house with two oldsters who every day faced with lots of monsters, aliens and ghosts. Courage ran and hid all the time, but every time when the two oldsters were in danger Courage would close his eyes to run back to rescue, for just all three could run together. Very cute.
Thinking about it, you have fears that you have no reason to eliminate. Like me, I have a fear of cockroaches. But that fear has no harm, so I have almost no motivation to eliminate it. After all, I still have the fear of cockroaches for decades. In fact, we have quite a lot of ways to overcome a fear, once we identify them, including fear of cockroaches.
