I can, therefore I am.

The dog that trots about finds a bone.

You never know what motivates you.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

Be kind whenever possible. It is always possible.

Either you run the day or the day runs you.

Do not weep do not wax indignant. Understand.

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