Fear of the unknown is overcome by an even greater fear of what will happen if nothing is done. Work that is easy or fun is put ahead of important work that is hard and painful. As long as we don't know where we are going, no one can fault us for not getting there. The less specific our plans and commitments, the less we feel we will be held accountable. Delegation requires human relations, skills in communication, trust, teamwork, and shared goals.
Procrastination is the death of great plans.
Without plans, goals remain beyond reach and dreams remain dreams. A friend of mine asked me what was my secret to being motivated. I gave what must have been a rather lofty but empty answer. My wife heard it and wasn't satisfied. The next day she came up with an answer that satisfied her.
