Stamp of Approval

What do you call love, hate, charity, revenge, humanity, magnanimity, forgiveness? Different results of the one master impulse: the necessity of securing one's self-approval. ~ Mark Twain

One master impulse - securing self-approval.
For years I tried devious, negative means,
never feeling approval from others, so not granting
my own. Then, dismissing the goal of crafting
others' acceptance, looking only to accepting me,
love, charity, magnanimity appeared bringing
validation all around.
