Yeah, commitment is scary stuff, I get where you're coming from.

Part of me wants to believe that as humans, we have this capacity to evolve all the time and therefore what worked in terms of a job, relationship, etc., at one point may not be a good fit for us later on. In that vein, it would seem natural to want to move around/try different things, see different places and so forth. Yet the other part of me says that in order to function as a grown up in the world, sometimes we have to suck it up and conform to routine, societal expectations and the like. And believe me, that line of thinking makes me very uncomfortable so I really can relate to a lot of what you're saying.

Could it be that at this job you're just not feeling very challenged? Do you have a sense of what you're passionate about in terms of what you'd really love to do for a career at this point in time?
