Putting all focus and consideration on others pulls away from the person that needs the attention most...YOU!  We say all things "self" from self-love, self-care, self-respect to self-improvement and completely leave out selfish. Why? Because it has been used of of context to be used not on self but to focus on how one is acting towards another person/s. 

We are that person that we lack consideration on. It's time to take control and look at this word selfish from a whole new perspective.
