To care for anything or anyone, you must understand it or him. Many people do not even understand themselves so as a result, they do not know how to properly care for themselves. They are abusive towards themselves and fail to do the things necessary to show the love and care that would bring themselves the very best things in life. Now by that, I don’t mean they beat themselves with sticks or run into walls repeatedly or other physically abusive things, but they make decisions that are bad, thereby putting themselves and those they love into precarious positions again and again. Addicts are a prime example of this. Many homeless people are like this. Certainly not all, but some.
