To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

Go for it now. The future is promised to no one.

Always desire to learn something useful.

If you're going through hell, keep going.

Be kind whenever possible. It is always possible.

Well done is better than well said.

If you think you can do it, you can.

The dog that trots about finds a bone.
