If you're afraid, the best thing you can do is admit it. Then you can move forward.
Hiding or suppressing fears doesn't allow us to actually face them. And the only way to get over a fear and become stronger is to face it, stare it down, and actually conquer it.
Speak truth to fear. Name the thing you're afraid of doing. Admit who you're afraid of becoming. Write down the place you're afraid to go.
That wasn't so bad, was it?
Now I bet you're one step closer to moving onward. Courage isn't found in figuring out how to live in denial; it's found in moving forward in the midst of the very thing you fear.
