Well done is better than well said.
It's always too early to quit.
If you're going through hell, keep going.
If you think you can do it, you can.
Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
Always desire to learn something useful.
I can, therefore I am.
The principles we live by, in business and in social life, are the most important part of happiness.
