It's always too early to quit.

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

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

Know or listen to those who know.

Well done is better than well said.

What you do today can improve all your tomorrows.

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

Always desire to learn something useful.

If you're going through hell, keep going.
