Experience is the name everyone gives to their mistakes. If you plan for a decade, plant trees. If you plan for a century, teach the children. The longer the island of knowledge, the longer the shoreline of wonder. Shallow men believe in luck.
Trouble is only opportunity in work clothes.
Getting ready is the secret of success. The pessimist sees the difficulty in every opportunity, the optimist, the opportunity in every difficulty. If wishes were horses, beggars would ride. Adversity comes with instructions in his hand. A diamond is a piece of coal that stuck to the job.
