Empty heads have long tongues. If every man would help his neighbor, no man would be without help. Yesterdays dreams are often tomorrow's realities. If you want to do your duty properly, you should do just a little more than that. Pessimism blunts the tools you need to succeed.
Optimism is a faith that leads to success.
A goal is not always meant to be reached, it often serves simply as something to aim at. One great cause of failure is lack of concentration. Showing off is the fool's idea of glory. If you don't want to slip up tomorrow, speak the truth today. Knowledge will give you power, but character respect.
