I have similar thoughts as you. I’m a pretty hard worker and also a self starter if I have goal in mind. I think I could do much better as my own boss because that in and of itself is motivating.
My first job out of college lasted 7 years and I was busy all the time. Everything was task based and there was always a million tasks to do so no chance for down time. Now im adjusting to a different work flow.
This is my job now and it's kinda starting to eat me up. I would love to be bored at work just one day.
