Some of us just hate having bosses. Being subject to someone's whims is such a repulsive feeling for me that I will go to great lengths to avoid it.

I actually even hate having dominant customers. My ideal model of business is a ton of smaller customers, with none of them having more than 10 per cent share of the total revenue.

Also, finding more ways to grow your business is rewarding - both psychologically and financially. I like "hacking" the question of "how can I introduce product X to more people who might be interested in buying it?"
