If you think you can do it, you can.

It's always too early to quit.

Without hard work, nothing grows but weeds.

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

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.

I can, therefore I am.

Problems are not stop signs, they are guidelines.

By failing to prepare, you are preparing to fail.
