I am reflecting over what self-care means, to me. 

I define it as a will and practice to give yourself what you need. To fill your own needs, but also be able to ask for those things you cannot do (for) yourself, or on your own, that is – to let yourself ask for – and receive help.

That definition rests on the assumption that you know yourself. If you do not know yourself, you cannot know what your needs are.
