Be gentle to all and stern with yourself.

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

Problems are not stop signs, they are guidelines.

Know or listen to those who know.

To know oneself, one should assert oneself.

Be kind whenever possible. It is always possible.

By failing to prepare, you are preparing to fail.

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

Well done is better than well said.
