Begin to be now what you will be hereafter.

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

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

It's always too early to quit.

If you think you can do it, you can.

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

Well done is better than well said.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.
