RE: Discovering myself
Of course everyone has bumpers. It's a matter of identifying one has. Not everyone contemplates on this, perhaps it comes with their personality. And most of the people who do these are introverts and find value in discovering oneself over others (perhaps being liked?).
Just to reciprocate, one of my bumpers is the want to be liked which has caused me to say yes to too many things when 'no' would have been the appropriate one.
