Wisdom is constantly fitting your dreams to your means. This reminds me of a story:
At the coffee-house, everybody was bragging of their military exploits.
“And you?” asked one turning to Nasreddin.
“I? One day, on the battlefield, I cut an enemy’s leg with one strike of scimitar.”
“Why not the head, as other people do?”
“That was impossible. Someone else had already cut the head.”
