Found the manager lol. Leading can be very easy or very hard depending on what the task is. For managers with a very narrow task and the benefit of having competent employees, being a manager is incredibly easy.

Not necessarily true.  As you get promoted, your tasks change. There are different stressors.  

For instance, say you work at Target in the Electronics department.  Your tasks are to stock the floor, help customers when the store is open, etc.

When you get promoted to Electronics manager, your tasks change.  You have to take direction from the store manager on how he wants the department to look and schedule your team of employees to do that.  You have to deal with the difficult customers that your employees need help serving.  You have all the answers and everyone looks to you for help.  You also have to represent your department with all of the other departments (stop taking my employees to run the register on the front end!). You are responsible for anything that goes wrong and have to figure out what to do when it does go wrong.

Different level of work, different stressors.

It shares similarities with the parent-child relationship.  Children don't understand all that a parent has to do, they think their job is easy and feel they are just told what to do and treated unfairly.  Until they become a parent and realize all of the things a parent does which they didn't even know was a thing (I think kids call it "adulting").

I used to think my boss was the stupidest person around until I got her position and realized what she actually did.
