If you think you can do it, you can.

Things do not happen. Things are made to happen.

Well done is better than well said.

It's always too early to quit.

The most effective way to do it, is to do it.

What you do today can improve all your tomorrows.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.
