Weakness = Strengths?

There's a thought going round that we focus too much on our weaknesses, which takes time and energy away from furthering our strengths. I understand the point, but I don't agree. More to my way of thinking is the belief that one's greatest weakness is also their greatest strength. In my story, which was published in the compilation book, Heart of Mother, I write of how Mama knew me and my brothers and told us about ourselves. Through playing cards, she pointed out my desire to win fast. You can read that story by clicking here http://kayshostak.blogspot.com/2009/09/addendum-for-todays-blog-heart-of.html
My three kids have weaknesses- (sorry for the sudden shock). One hates making decisions, one is an instant expert, and one has never met a good change. But those are also their strengths. Not making decisions quickly means all sides are examined and many options usually come to light. Being an instant expert, means being confident and ready to lead. Disliking change makes that one laid back, easy going and comfortable to be around. Who better than parents to tell their kids who they are - good and bad.
Me being aware of my desire to win fast had helped me know myself. The strength in that flaw? I'm a mover. When something is wrong or messed up, I gotta get involved. Often I've lamented that I hate to find a problem, because I can't rest until it's fixed.
So knowing our strenths AND weaknesses makes for better knowing ourselves. I heard this thought one time and liked it so much it still hangs on my refrigerator door.
"Walk in your strengths, manage your weaknesses."
