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

Know or listen to those who know.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

Who seeks shall find.

Begin to be now what you will be hereafter.

If you can dream it, you can do it.

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

It's always too early to quit.
