If you think you can do it, you can.

Know or listen to those who know.

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

Without hard work, nothing grows but weeds.

Begin to be now what you will be hereafter.

I can, therefore I am.

Things do not happen. Things are made to happen.

Problems are not stop signs, they are guidelines.

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