I can, therefore I am.

To know oneself, one should assert oneself.

Know or listen to those who know.

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

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

If you think you can do it, you can.

Never complain and never explain.

Begin to be now what you will be hereafter.

Problems are not stop signs, they are guidelines.
