I can, therefore I am.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

Know or listen to those who know.

Be gentle to all and stern with yourself.

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

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

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.
