I love these management gurus that have these flowery words for what we might use more plain and simple words. Think problems. They call them "challenges." Well
With Challenges Put Your Thinking Cap On.
Challenges allow us to grow by overcoming them and also learning the lesson from them. I can't sell this house of mine. That example I would say is a problem, ahem, challenge. You need to come up with many directions of how to overcome it. I guess if you have to bail yourself out with a lot of cash at the closing table being underwater with your loan balance and the sale price there is a lesson there, like don't buy an overpriced house or maybe you shouldn't sell in a down cycle. But for every "challenge" there are multiple options to solve it.
Some of the people that go the farthest in life are the best at solving problems and even finding the optimum solution.
So toss the dunce cap, don the thinking cap, and knock those challenges out of the way, one by one.
