There's a story about a dog that bragged about his running speed. One day he chased a rabbit, but failed to catch him. The other dogs ridiculed him. He answered: But remember, the rabbit was running for his life. He had a motive. I was just running for fun. If you're just working for fun or wages you'll never try as hard as if you're working for a deeper, longer goal.
More people fail through lack of purpose than from all other causes combined.
The truest shortcut to success is to set a Goal.
