Commitment.

“Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiation (and creation) there is one elemental truth, the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then Providence moves in too. All sorts of things occur to help one that would never otherwise have occurred. A whole stream of events issues from the decision, raising in one’s favor all manner of unforeseen incidents and meetings and material assistance, which no man could have dreamed would come his way.

Whatever you can do,
or dream you can, begin it.
Boldness has genius in it,
power and magic in it"

-- Goethe
