Sacrifice for one's self, the type Ebola is talking about, is different from sacrifice for others.
There is a fundamental difference. And sacrifice for others is vastly superior. In fact, it is necessary in order to live fully.
"Only a life lived for others is worth living." - Einstein
This is because self-sacrifice is actually partially a trick.
"Self-sacrifice is never entirely unselfish, for the giver never fails to receive. " - Dolores McGuire
When we are referring to self-sacrifice, it is not real sacrifice. It may seem like sacrifice (at least temporarily), but it is just part and parcel of our power to achieve anything - in this way it is like the materials necessary to cast a magic spell. It is our choice to use the materials in order to cast the spell, and do the magic.
“Dreams do come true, if only we wish hard enough. You can have anything in life if you will sacrifice everything else for it.”
― J.M. Barrie, Peter Pan
“Real magic can never be made by offering someone else's liver. You must tear out your own, and not expect to get it back.”
― Peter S. Beagle, The Last Unicorn
In fact, self-sacrifice is not only what we use to attain what we want, but by using it, we strengthen our selves, and move toward happiness.
"Many persons have the wrong idea of what constitutes true happiness. It is not attained through self-gratification but through fidelity to a worthy purpose." - Hellen Keller
“Sacrifice is a part of life. It's supposed to be. It's not something to regret. It's something to aspire to.”
― Mitch Albom
In fact, it is intricately linked with love (in the case of self-sacrifice, it is linked with self-love).
“You can sacrifice and not love. But you cannot love and not sacrifice.”
― Kris Vallotton
