If you think you can do it, you can.

If you can dream it, you can do it.

Begin to be now what you will be hereafter.

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

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

It's always too early to quit.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

Expect problems and eat them for breakfast.
