The lesson is if you keep trying and things don't open up, stop doing it. Look up. Look around. Try something else. Think--there is an opportunity here for me! Look and see where it is. Then go in that direction.
We all do this. It's the easiest way to create a problem where there is no problem. You keep trying, wondering why it doesn't work. You see a therapist to help you make it work. Time passes, now you're moaning about how things didn't work out. You've built up a history of things not working out. Phew! Exhausting. When all along, it's not your path anyway, the path is elsewhere.
So, if the road keeps being blocked after trying a few times, look for another road.
