It's always too early to quit.

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

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

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

After a storm comes a calm.

The secret of getting ahead is getting started.

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

Well done is better than well said.
