"In the land of the blind, the one eyed man is King" - Erasmus

In entering trades consider beforehand what vision and edge you truely have. Getting caught up in a buy of a mature trend hoping that others will be greater fools than you takes no patience.

Sometimes a trade will present itself which you could not have waited for or expected and the thing not to do would be to pass on it, waiting for it to become perfect. Perfect opportunities rarely exist. Waiting for perfection on earth or in the markets might exceed anyone's patience.

It would be prudent in your trading approaches to find situations where you are the one eyed man in the land of the blind.

Don't trade where you need the vision of an eagle on a crisp autumn day, you seldom will have the reflexes to match your vision anyway.

Look for opportunities where you can profit from the exhausted sight of others.

Another analogy might badly mix with this one: don't attempt to pick up nickles in front of Bulldozers with a blindfold on. If you can't see and understand an opportunity, wait for the next one.
