The more you talk about negative things in your life, the more you call them in. Speak victory not defeat.

Don't be so quick to believe what you hear because lies spread quicker than the truth.
I do not believe in a fate that falls on men however they act; but I do believe in a fate that falls on them unless they act.
Wise men speak because they have something to say; fools because they have to say something.
It is better to remain silent and be thought a fool than to open one's mouth and remove all doubt.
The trouble with talking too fast is you may say something you haven't thought of yet.

The right word may be effective, but no word was ever as effective as a rightly timed pause.
