Know or listen to those who know.

To know oneself, one should assert oneself.

You never know what motivates you.

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

It's always too early to quit.

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

Problems are not stop signs, they are guidelines.

Without hard work, nothing grows but weeds.

Begin to be now what you will be hereafter.
