It's always too early to quit.

Know or listen to those who know.

If you think you can do it, you can.

Go for it now. The future is promised to no one.

Problems are not stop signs, they are guidelines.

Be kind whenever possible. It is always possible.

To be a good loser is to learn how to win.

By failing to prepare, you are preparing to fail.

Well done is better than well said.
