Thought, intention, action. Detach yourself from the immediate outcome, but instead ask yourself a better question: 

What am I trying to achieve here? What is my intention?

Indecision is a vice, because the outcome is not under your control. Examine your intentions, then act at once. If you do this, the outcome will be information for you to use, not a judgment about your worth.

Detach your Self from the immediate outcome.
