"Then indecision brings its own delays, And days are lost lamenting over lost days. Are you in earnest? Seize this very minute; What you can do, or dream you can do, begin it; Boldness has genius, power and magic in it."
This is often attributed to Goethe, though it is more properly attributed to John Antser
Goethe definitely sad this
"This altercation’s gone on long enough, it’s time I saw some action too! While you are polishing fine phrases something useful could be going on. What’s the point of harping on the proper mood? It never comes to him who shilly-shallies. Since you pretend to be a poet, make poetry obey your will. You know that what we need is a strong drink to gulp down fast, so set to work and brew it! What’s left undone today, is still not done tomorrow; to every day there is a use and purpose; let Resoluteness promptly seize the forelock of the Possible, and then, reluctant to let go again, she’s forced to carry on and be productive."
Either way. Go. Do it. Whatever it is.
