Having a secret is like hiding.
You have to keep "looking over your shoulder" to make sure no one finds out.
Secrets keep you on edge, nervous, suspicious, paranoid.
When I purged myself of my secrets it was a huge load off my mind. Continuing to do the next right thing helps keep me emotionally healthy and spiritually fit.
I have said it before that when I decided to "come clean" about myself and then live a moral life, much of my self centered fear and self loathing vanished.
It may have been the single most important decision I have ever made.
