Castlepaloma ~ I think we do indeed need to attend to ourselves, to keep ourselves (internally and externally) in a place where we can aid others, etc - but, I think the oft heard notion that 'we have to love ourselves first if we're going to love others' type sentiment is misleading or misplaced . . . being content about, satisfied with, loving ourself, etc, is (I think) supposed to be a kind of base norm, the idea that what we need to learn and do is love ourself is, again, misleading and misplaced - we need to get over ourselves and learn to love others.
It's like, to me, saying that the evil of the KKK is the hatred they practice toward green, that they butcher trees so they can burn crosses - that is certainly a waste of a natural wonder and resource, but it's not the evil that needs tended to first and foremost regarding the KKK. Yes, we need to be emotionally sound and own a right sense of self, etc, but when we announce that 'we need to love ourselves if we are going to love others' I think we miss the real issue that hinders us - what we need is to overcome our own self-interest and learn to love others.
I don't think any particular percentage of attention given to our own needs compared to the needs of others is right or wrong, the young entrepreneur, laborer, or whatever needs first to tend to his own immediate responsibilities, take care of those under his care revealing other's resources to go to those in need and then contributing what he can. selfishness isn't necessarily about how much you take or how much you give, but why you do what you do . . . some work hard and give much to charity, not so that those in need will be revealed from hurt but so that others will think well of them - that is selfishness, thinking of your own desires and interests above the welfare of others.
