If you're getting ready to hire someone new or add a person to your advisory board it is easy to look for someone with whom you'll get along.  That, however, might not be the best choice.

What you often need is someone who can compliment your weaknesses  and fill in the blanks in your skill set.  Very often the person who does that is the Yin to your Yang.

They're your opposite and so while they bring that fresh perspective and different skills they can also make you a little crazy because they're not going to see the world the way you do.

But, if you want to grow your business you need that other perspective. You need people who will challenge your ideas,  make you think and see the world in different ways.
