I'm in a very similar situation, and I don't think it's the "hedonic treadmill" as others have suggested. I believe the key here is you saying "I dream about doing my own thing or retiring early to do other projects.".
I, personally, have a ton of different interests, yet have to spend most of my time doing only one (my job). I also help around the house, spend time with my wife and kids, etc. But that means very little time to pursue most of my interests (and when I have time, I don't always have the energy). I don't think you're wanting "more" in general, just more freedom to do other projects that interest you.
I know I personally yearn for the day I can retire and work on whatever I want. Unfortunately I won't be retiring early, so I'm doing all I can now to make sure I can retire comfortably and have the money I need to allow me to pursue my interests. To help in the meantime, I'm acknowledging each little victory towards that goal and also trying to organize/automate other things in my life to allow me to have more time now.
