Things do not happen. Things are made to happen.

Problems are not stop signs, they are guidelines.

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

Either you run the day or the day runs you.

Never complain and never explain.

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.

I can, therefore I am.

To know oneself, one should assert oneself.
