A lot of human unhappiness is caused by thoughts of what the world and the people in it owe us. These thoughts are caused by the world view – “I am a good person. I’ve done good for … and, so, … owes me for it.”
This world view causes expectation and this expectation results in inevitable disappointment. It is also foolhardy for many reasons; the first of which is that we vastly over estimate the effects of our actions.
Things get much better when we internalize 2 truths –
1. Nobody owes you anything (no, not even a thank you)
2. It is actually you who owes the world and its denizens. You take up space (physical and emotional). And you better have something good to show for it.
So, get over it. Get sh*t done. Be happy.
