I can, therefore I am.

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

Never complain and never explain.

What you do today can improve all your tomorrows.

If you're going through hell, keep going.

Problems are not stop signs, they are guidelines.

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

To know oneself, one should assert oneself.

Know or listen to those who know.
