If you think you can do it, you can.

I can, therefore I am.

If you can dream it, you can do it.

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

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

Either you run the day or the day runs you.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

After a storm comes a calm.
