I once worked with a young lad who had exactly complimentary skills to mine. Together we made the perfect team as we shared the same values and would happily shunt the workload between us to whoever was best suited to handling the task or customer. This compatibility meant that, although only two people, we were probably as effective as three.
I’m afraid that I spoilt the dynamic when I went off to have babies and then moved to France.
Roll forward several years and my own kids operate as a power team as one thinks linearly and precisely, while the other is a problem solver who thinks so far outside the box that they don’t even realise that there is a box. For years now their combined efforts have been enough to outwit most adults. (It’s also why I have so many grey hairs just from trying to stay ahead of them).
Even if you never discover such a perfect pairing it is worth having a diverse team who bring different skills and ideas so that the combined efforts are much more than the sum of the individuals.
