Ask HN: I love freelancing. Then why do I hate it?

I've been freelancing all of my working life and thus have (luckily) built a solid reputation & network that allows me to ask for generous sums of money for project without me working long days. So I am earning a nice living that I'm very very thankful for.

However... why for the last 5 years have I tried launching a gazillion projects with the hope of leaving my clients behind and create a more 'passive' and more scalable source of income?

Why do I on one hand, love working with people. But at the same time don't want to abide by their rules anymore and do my own thing.

Is there anyone around here that managed to successfully transition from that level of freelancing to being a business owner of some sorts that is earning them more from freelancing AND is actually more enjoyable?

I'm torn by the daily switch of love/hate of my day to day work.
