Self-love and self-care are unbelievably important. And yes, there is a difference. But first, let me just clarify some things: It is not selfish of you to look after yourself and it is not egotistical to love who you are and what you look like.
I encourage you all to listen to your bodies. The recommendations on nutrition, from a little chocolate to strawberries to some chicken or even... beetroot, are usually entirely rational and are probably fairly important.
