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

It's always too early to quit.

I can, therefore I am.

If you think you can do it, you can.

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

If you've got a talent, protect it.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.
