"risk aversion is really just about our resistance to change."
So much this. When people think of attachment, we always point to material possessions, not jobs, people... beliefs. In a way "playing it safe" is the coping way of saying that we want to handicap our life experiences instead of risking it for more.
I feel that the assumptions surrounding changing our life choices isn't risk—as there is always something to gain. It's just a way we convince ourselves to remain in emotionally draining lifestyles while passing up chances and opportunities to change it.
It's fun to not know exactly what's in store for the future. We get to become more creative! :D
