This meme reminds me of the movie "It's A Wonderful Life" starring Jimmy Stewart.
Live a life that matters. Live a life of love.
I imagine it would be difficult to be consistently kind to yourself, and to others, if you were not coming from a perspective of love. Love of self, love of friends and family, love of strangers, love of humankind.
The impetus for being kind is birthed in the spirit. Kindness comes from a place of compassion, of understanding, of patience. Kindness results when we imagine what it must be like, would be like, to be in a place of need and we respond with kindness because we know that is the balm that would (and does) sooth our battered spirit in that same circumstance.
Kindness is both selfish and selfless.
Kindness is the conscious act of building toward that end of life where we can say, I did OK. Easing of burdens for self and others is seldom costly except in time and effort. And, oh, the incalculable rewards that result!
Live a life of love.
