Studies show that self-employed people experience more well-being. They’re more satisfied with their work, and that’s likely attributed to a higher degree of autonomy and independence. As they say, do what you love and you’ll never work a day in your life. 

We found this article from way back, that still applies today. Here's the abstract...

"The self-employed are substantially more satisfied with their work than employed persons. We document this relationship for 23 countries and show that the higher job satisfaction can mainly be attributed to the more interesting jobs and to the greater autonomy that self-employed persons enjoy.

‘Doing what you like to do’ seems to provide non-pecuniary benefits from work suggesting the existence of procedural utility: interesting work and autonomy are valued beyond material outcomes as good procedural work characteristics. The results hold for western European, North American and eastern European countries, but largely also for countries with a non-western cultural background."
