I wish more people paid attention to that. More often. A lot more often. In the way of looking at it like an ongoing continuum, instead of one big event.
Of course, you would never be able to make others feel good if you did not love yourself and your life.
So, the source of loving others is truly rooted in unadulterated, purest yet non-delusional self-love. To love and accept yourself fully, while not being blind about your blind spots.
Life is really that simple. You make yourself feel good by doing the hard things. And you make others feel good by making life easier for them.
It is only when we do not pay attention to making our lives better that our (and everyone else’s) lives turn miserable.
