Step-by-step explanation:
People shouldn't be selfish for themselves, they should take care of their body and mind as its best. Everybody should eat healthy food and live a healthy life because in that way not only that body is looking good, we are feeling good and we are happier.
A person who loves itself can love and be kind to others. People should not be so harsh about themselves because they must try to understand the environment that they grew up in and the positive path that they will take can change over the night.
The best thing for us is to take care of ourselves, eat healthy, be kind and educated. There are no people with the same life and childhood and because of that, it is important for us to understand the others and also to understand us.
