Never complain and never explain.

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

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

By failing to prepare, you are preparing to fail.

It's always too early to quit.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

If you're going through hell, keep going.

Always desire to learn something useful.
