Without hard work, nothing grows but weeds.

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.

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

If you think you can do it, you can.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

I can, therefore I am.

Problems are not stop signs, they are guidelines.
