@Greatest I am,
Multiple reasons...to move towards self-actualization, to gain benefit, to be loved. Your parents, significant other, etc. cannot help be but what they are and you adore, worship, and honor based on the sustenance and love, i.e. value they have provided. Also, if you fail to adore, worship, and/or honor, then that which cannot help but be what it is, may just decide to kick you out on the street.
I don't adore, honor, or worship a pebble in my shoe because it has no value to me. Things that have value, that provide a benefit are honored.
