Quality is not an act, it is a habit.

By failing to prepare, you are preparing to fail.

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

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Problems are not stop signs, they are guidelines.

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

If you think you can do it, you can.

To know oneself, one should assert oneself.
