If you can be truthful to yourself you can be truthful to others. Nobody else is judging you but you. In order to grow positively you need to sit in silence for 5 minutes and think about what happened, why it happened. Close your eyes and remember what you did. Prepare to let go now.
Let go of any negative energy that was associated with any past event of your life be it personal or professional. Forgive yourself for holding on to that negative energy and say to yourself, “I forgive myself as I forgive others from now on I am releasing all the negative energy associated with this particular event.”
