This, I agree with. In general, very few companies make up a large percentage of the profits, illustrated perfectly by the whale curve. It is quite shocking to see that thing pop up when you run it across real data, but it shows you instantly who to keep happy.

It's a terrible strategy to play Pokemon (gotta get 'em all) with your business. No matter how hard you try, you simply cannot increase profits over certain customers and you risk collapsing your profits if you place your effort there.
