There is a puzzle to solve, but solving it doesn't have to be beyond your reach. It doesn't have to be a terrible struggle. It can be a time filled with growth and new adventure-and winning. Time after time your resolve will come under deep scrutiny. An obstacle can appear like a brick wall set across your entire path.
Resistance can bring moments of deep discouragement.
That's mainly because the resistance often inspires confusion and doubt. It's the belief that an obstacle is saying your goal isn't meant for you. Avoid the disappointment. You'd be much more reasonable to drop your pursuit and take it all a little easier. So the true key to obstacles is this.
