Yes, I have always had a sense of restlessness, a need for change. When my life becomes stagnant, I get bored & then unhappy. A lot of people respond to stability in their life by creating personal dramas, but I hate that stuff also. When I think about the most stable time in my life, when I lived on my own, had a good job, kept a regular schedule, etc - I was not terribly happy. I definitely felt something was missing. I wanted stability with people, but not necessarily circumstances.
I think NFPs need to be constantly growing in life or dissatisfaction sets in. Regarding Ne, Jung says the Ne-dom constantly wants to pursue the next idea, at the expense of what already is, and compound that Fi idealism, and you get someone who is always searching for something better. It's simply a part of the mindset to want to move forward into some hypothetical, perfect future. I know for me, stability comes in my relationships & my spirituality. When it comes to what I am doing every day though, I need that to encompass a variety, to be changing, so I can keep learning & exploring different things. If I do feel stable in those previously mentioned areas, then I also feel braver to take the chances where I want to take them.
I haven't been dating my current bf that long, but I'm happy to say that we share life goals of NOT having kids & a house. There's nothing wrong with that stuff, but it can chain you down. I'm sure there are a lot of ways you can still pursue new things, but it's harder to not get caught up in the everyday mundane. We both want to be able to pick up and move to whatever opportunities might come along. When I was a teen, I fancied my adult life to be some bohemian, nomadic lifestyle where I pursued what I loved without having to call it a career; I'm coming back around to that mentality.
I've also realized that if possible, I'd rather not take a 9-5. I also tried my own business for a time (and tasted freeeeedom! but also debt...), and haven't been able to get steady freelance design, but I'm still looking for avenues which give me flexibility to pursue other stuff when not working. Instead of changing careers a lot, looking for the holy grail job, I figure it just won't be the focus of my life or my identity. Since I'm generally content with a modest income, I think this is possible. I want as much time as possible for things that really matter to me, and it's more realistic to do that on your own time, not an employer's clock. The hardest part is probably keeping a simple lifestyle, so you don't require a lot of money to maintain it.
