Do you believe that when you are your own boss that you don't have to work for someone else anymore? If you do that you should think again. Every entrepeneur is working for their customers. If the customers don't buy the products or services anymore there is no business. You might have more freedom with some of your decisions but you need your customers.
As a Manager (on whatever level) you work for whoever owns the company or the next level above you. In that case you might be less concerned with customers but you still have someone you are working for.
This will be the case for 99% of the population. Instead of fighting or denying this fact it is better to actively search situations where you can work for someone because you share the same values most of the time.
