I didn't mean to love everyone as if they are your future life-long partner, I mean it in more of a way like this- someone cuts you off driving, and naturally you want to get mad and curse them. Instead, in the name of love we should strive to face this with optimism and love for the human behind the wheel. It is a hard thing to do! But if we strive to love, love will eventually become our second nature, instead of the seemingly inborn tendency to react with negative emotions.
Love can be simple acts such as refraining from speaking ill of others, refusing to hold grudges, becoming angry, jealous, spiteful, smiling at a stranger, etc. It does not have to be an extravagant thing that we all hope for, but rather a real driving force that allows us to make uplifting choices every minute of the day- both for ourselves and others.
