Generally speaking, it’s easier to be kind when people are kind to you. You worry less about your kindness being wasted or unappreciated, and you don’t fret about being taken advantage of when you can see your kindness being returned, even indirectly.
People talk about how one small act of kindness can have a lasting impact or how you get the love you give, and a lot of that does sound like motivational poster horseshit or Western culture bastardizing Eastern theology.
But to be charitable, I think this is all they mean—being kind to people helps them care for others fearlessly. It helps people overcome some of the insecurities and worries that stop them from exercising their selfless, compassionate, empathic impulses and lets them, at least for a moment, tap into a better part of themselves.
And it’s one of the purest acts of love to help someone have as many of those moments as possible.
Have a happy Valentine’s Day. Be kind to people. And go get laid maybe.
