Circumstances may cause interruptions and delays, but never lose sight of your goal.
Mario Andretti

Desire is the key to motivation, but it's determination and commitment to an unrelenting pursuit of your goal - a commitment to excellence - that will enable you to attain the success you seek.
Mario Andretti

Do it no matter what. If you believe in it, it is something very honorable. If somebody around you or your family does not understand it, then that's their problem. But if you do have a passion, an honest passion, just do it.
Mario Andretti

Everything comes to those who wait... except a cat.

If everything seems under control, you're just not going fast enough.
Mario Andretti

If you wait, all that happens is that you get older.
