When you look at a highly successful person, you think you're judging him by his success, when in actuality, all you're really seeing is his endurance of pain.
If you view your attainment of goals this way, you'll be amazed at how powerful and confident it feels. It becomes a total win / win situation, knowing that when you succeed or fail along the way ... you're really only succeeding.
There's no such thing as a straight line, and there's definitely no such thing as a row of unlocked doors. This is the beauty of struggle - figuring out ways to make the path straighter and doors open!
