Well done is better than well said.

If you think you can do it, you can.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.

The wise does at once what the fool does at last.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

Problems are not stop signs, they are guidelines.
