An altruist is not just a good person who does good deeds from the heart. It is a person who consciously puts the needs of others above their own. Altruists try to make the world better not only for themselves but also for those around them. If you help someone without expecting thanks or a return, then that is already about altruism.
Altruism has synonyms that may surprise you. For example, charity, self-sacrifice, or even selflessness. These words reflect different facets of altruism. Imagine a situation: your friend is in trouble, and you, without hesitation, decide to help, even if it requires sacrificing your time or money. That is true altruism.
So an altruist is more than just a good person; it is someone who lives by the principle of “do good and throw it into the water,” as the main thing for them is to support and help.
