The artists of the world can certainly agree with these words. They ring true, but no matter how many times you hear them it may not help you to change. Imagination and action are very different states of mind. When your imagination is soaring, you are overwhelmed with positive ideas, possibilities, and sometimes the abstract.
When you are accomplishing, or doing, you have to tame down these wild, free-flowing thoughts in order to get anything done. Sometimes it hurts to hinder our imaginations in this way, but think of it as a gentle harness, allowing you to take your imagination (and great ideas) further than you’ve ever imagined.
