To know oneself, one should assert oneself.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

If you can dream it, you can do it.

By failing to prepare, you are preparing to fail.

Well done is better than well said.

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

Know or listen to those who know.
