Absolutely Fiver. And also, don't talk yourself into settling down just because other people say you should. Perfectly healthy adventurousness and curiosity are often put down as unhealthy restlessness; the two are not the same thing. If you have the first one, don't let others persuade you to repress it on the basis that they think it's the second.
I've learned that trying to force myself to settle down means that I just end up sticking with something purely to try to prove people wrong about me being restless or unable to stick at things - even when this thing is harmful to my psyche and there's no logical reason to continue with it. It causes me to end up putting up with a feeling of repressedness and boredom that causes me to actually BECOME restless, so that I eventually just can't take it any more end end up just having to break the fuck out and just create total upheaval to just GET OUT OF HERE!!
I've learned to embrace my need for changes of scene, for adventure and changes of direction, for refreshment and renewal. And that these things are perfectly valid parts of my personality that are not problems or flaws, but only become seen as problems when I'm forced into a situation where they're not able to be expressed. I do not have problems with commitment and I am not a person who wants to run away from their problems. When I explore it's not escapism.
Therefore, I've learned to make sure that whatever I do, whatever job I'm engaged in, either the job itself must contain the possibility to discover new things, new places, or it must leave me with enough leisure time and resources to do so in my spare time. It doesn't mean you have to run off to different countries and blow off your responsibilities. I've lived in the same town for 10 years now (a personal best lol), but the way that I can stay sane with all this sameness is by having a) different groups of people to socialize with, in different scences, b) going out to explore randomly a lot, from long distance vacations to driving to a village I've just spotted on the local map and just rambling around it, checking everything out and talking to the people I find. And then after I've done that, I come back home. And c) my work has always entailed a high level of unpredictability and, when I'm there, high pressure. And it's always been something I've believed in, something I'm passionate about.
Working in the charity/humanitarian sector satisfies all three needs: making a difference/improving the world; variety and challenges that require creative thinking; frontlining it, getting my hands dirty (being there amongst the people). It also often entails travel to different areas and frequently working with new teams, different people.
Your need for adventure, challenge and new scenes is an integral part of your personality and is valid, valid, valid. Don't ever let anyone persuade you otherwise, or you'll end up committed to a lifestyle that kills who you are slowly from the inside.
