"Love", as found in Koine Greek, is "agape", which has a different translation that no English word adequately covers. It's considered an active noun, so one doesn't just have love, they live love.Actually there were two:
1. To love God with all your heart and,
2. To love your neighbor as you love yourself.
There was nothing inherent in these commandments about doing anything else, no matter how altruistic you want to be. Even Yeshua knew he couldn't change nor save the physical world.
The big problem here is that most people have no idea how to love themselves, this was the secret in the second commandment; and you have to love yourself before you can love another. Once you learn how to really love yourself everything else falls into place.
Also, love of one's self is not necessary but is recommended. One may perceive too many flaws in themselves and yet still love others.
One of my granddaughters is this way since she suffers from "mood disorder" (similar to bipolar disorder like my son has), so she's way too self-critical, and yet she has a heart of gold towards others, doing volunteer work dealing with disadvantaged children for about five years now.
