Sometimes I feel like my life would be easier if one day, I just got on the bus and went away somewhere and left everything behind - my family, my friends, my belongings, my identity, everything. It's not that my life is bad - on the contrary - it's a perfectly good life that in many ways I am extremely grateful for. But apart from the impracticalities of that action (I would most probably not be able to create a new identity successfully or be capable of supporting myself and would end up homeless), what is stopping me? What stops me from taking huge risks and following impulses? Why should I stick to what is normal, or proper, or expected? I'm not asking a psychological question - I am curious to know the philosophical elements, if there are any. Why don't most humans follow their urges?
