Don’t neglect yourself and your health to avoid feeling selfish. Selfishness doesn’t have to be a bad thing. It can be good to be a little selfish to take care of your emotional, mental, and physical well-being. Many people who focus entirely on give, give, give end up overwhelmed, fatigued, and stressed. And chronic stress has been linked to a number of health risks, including conditions like diabetes, cancer, and mental illnesses, plus unhealthy eating and putting on weight.
