Om Swami
How can I find strength when I am afraid of admitting my mistakes?
Admit your mistake and take a small vow of truth
Telling the truth requires strength, and admitting a mistake gives you strength. Resolve not to lie for the next three days, no matter what, and stick with it. Then you will gain the strength.
But if you confess, if you admit, "Look, I messed up. I plan to do it differently." It will give you strength.
