If you are unsure of a course of action, do not attempt it. Your doubts and hesitation will infect your execution. Timidity is dangerous. Better to enter with boldness. Everybody admits the bold; no one honors the timid.  

Boldness gives you presence and makes you seem larger than life. The timid fade into the wallpaper, the bold draws attention, and what draw attention draws power. We cannot keep out eyes of the audacious - we cannot wait to see their next bold move.

When you take time to think, you create a gap that allows other time to think as well. Your timid infects people with awkward energy, elicits embarrassment. Doubt springs up on all sides
