You probably never heard of someone being called a “Know-it-Sum” – you probably only have heard of know-it-alls. I prefer to surround myself with people who know it sum.
A know-it-sum is someone who knows how it all adds up, but doesn’t claim to know it all. They know that a sum of parts is far greater than one whole in many cases, and knows that it takes a team to make a dream a reality.
One person who claims to know more than anyone else tends to stand out like a sore thumb, but someone who is a know-it-sum knows that they must rely on others to fill the gaps.
Know some, be a know-it-sum.
