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

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

Either you run the day or the day runs you.

It's always too early to quit.

Know or listen to those who know.

Be thine own palace, or the world's thy jail.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.
