To know oneself, one should assert oneself.

Know or listen to those who know.

Be gentle to all and stern with yourself.

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

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

By failing to prepare, you are preparing to fail.

Without hard work, nothing grows but weeds.

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

Never complain and never explain.
