What is the secret of choosing and maintaining the direction?
While discussing this topic, I often remember 150 years old conversation in Alice's Adventures in Wonderland classic.
Alice (a girl who is lost in the woods): "Would you tell me, please, which way I ought to go from here?"
Cheshire Cat (a character who lives in the woods): "That depends a good deal on where you want to get to."
Alice: "I don't much care where"
Cheshire Cat: "Then it doesn't matter which way you go"
