Nobody taught me how to steal, lie, make excuse, blame someone/something else, cheat, envy, become jealous, bear false witness, insult ... I knew how to do these things from birth. Ever notice you can "spoil" a child simply by allowing them to do what they want to do? To counter those inherent traits we're taught through repetition not to do them. We hone some of the adverse traits to a fine edge throughout our life even though we are taught not to do them. We become much better at trying to get away with things, blame someone/something else, gossip against someone, how to lie and mix some truth in to disguise it... in short, how not to get caught and still get whatever it is we are after. The good things don't come so easily since doing good doesn't satisfy the sinful nature as much as doing the things that come naturally from the start.
Yes, one can get a warm, fuzzy feeling from doing some "good" here and there but in a lot of those cases the ego is bolstered none-the-less. And doing good in secret is not something many are prone to do. We need applause, recognition or honor of some kind to enhance our self-pride, build ourselves up, to gain approval from the world. The bad things we do in secret, the good we want the whole world to know about.
Living in an apartment building some years back a woman put canned food out at the laundry room for those who wanted/needed it. That was good because quite a few living there couldn't afford much. But, rather than let that be as may she had to pin her picture above the "donated" food.
