I've thought about it and I only care about myself.
What made you come to this conclusion?
Ah, I've always been like that
Making sure to treat yourself well is very smart, not enough people do it. But, you have to think about the needs of everyone else around you as well.
I only care for myself.
While you should make yourself a priority, it's important to care about other people. Your family, your neighbors, your friends, even strangers you will never meet: everyone matters. Don't neglect yourself, but try to be compassionate for others as well.
