The Rule of 3 and 10
One of the best pieces of advice I ever received came from Hiroshi Mikitani, the CEO of Rakuten. He said everything changes at roughly every 3rd and 10th step.
When you go from one person to three people it’s different. When it’s just you, you know what you are doing — and then you have three people and you have to rethink how you are doing everything.
But when there are ten people, it’s all going to change again. And when there are 30 people, it will change again. Same when you reach 100 people.
At every one of those steps everything kind of breaks. Everything. Your communication systems, and your payroll, and your accounting, and customer support. Everything that you put into place needs to change when you put in those three and 10 steps.
