To know oneself, one should assert oneself.

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

It's always too early to quit.

Without hard work, nothing grows but weeds.

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

You never know what motivates you.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.

Quality is not an act, it is a habit.
