To know oneself, one should assert oneself.

The dog that trots about finds a bone.

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

I can, therefore I am.

Be thine own palace, or the world's thy jail.

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

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

Be gentle to all and stern with yourself.

It's always too early to quit.
