You can’t judge yourself based on other peoples perceptions. Most of the time don’t give up. Know that in the beginning you will fail, but keep the goal on the horizon and don’t let the little stuff knock you of course. If it fails look at it, examine it and know that something must change if you want things to change. You can’t expect things to change if you do not change.
Take a new action, add something, tweak it, etc. Ask yourself why and look at the what, where, and how. Remember to remain objective and don’t let a temporary emotion take over. Keep your eyes on the horizon.
