As a doctor, let me tell you what self-love does:
It improves your hearing, your eyesight, lowers your blood pressure, increases pulmonary function, cardiac output, and helps wiring the musculature. So, if we had a rampant epidemic of self-love then our healthcare costs would go down dramatically. So, this isn’t just some little frou-frou new age notion, oh love yourself, honey. This is hardcore science
If you want happiness for an hour – take a nap. If you want happiness for a day – go fishing. If you want happiness for a year – inherit a fortune. If you want happiness for a life time – help someone else.
