You are right, and that kind of brings up the whole argument of "But then isn't everything selfish?" and I'd say not really because if you can see how connected we are, you realized that when you truly benefit yourself (and not simply in an egoic way, with love rather than fear, and with a belief in abundance rather than lack) you will be most capable of benefiting others as well and helping them along the way in ways you don't even realize at the time. Telling someone how you really feel, for example, will give them an opportunity to face their own truths.

I had just heard something like this when I was listening to Abraham Hicks yesterday. :-D
