If you think you can do it, you can.

It's always too early to quit.

Either you run the day or the day runs you.

Know or listen to those who know.

You never know what motivates you.

If you're going through hell, keep going.

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

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

To know oneself, one should assert oneself.
