For people who are doers — you know, those seemingly super-beings we rely on to make our world turn — obstacles are the enemy, the Anti-Progress. When a barrier is thrown in a doer’s path, it’s easy to get stuck as a Perplexed Planner, with all the tried-and-true methods failing to make headway.
But the absence of obstacles in life is also Anti-Greatness. If we’re never challenged, it’s unlikely we’ll be driven to improve or innovate. So from a things-can-always-get-better perspective, obstacles are good for us. They cause us to think differently so we can clear them up and go about our even-more-productive way.
