As they say “a bird in the hand is worth two in the bush”. To expand on that a little, to keep the bird in your hand you need discipline, and to get the bird in the bush you need daring.
When starting a new business, daring is in abundant supply, and inspiration performs the role of discipline. But in order to succeed, you need to develop discipline before the inspiration wears off.
