QUICKTAKE: I wonder, do we just live, just move and move and let life happen? How intentional are we with our lives or is everything just automatic? Do you ever ask these questions of yourself? If not, perhaps you should reach down and click off the auto-pilot and grab hold of the wheel.
Another thing that jumps out at me about this is how self-oriented we are, some people are. Honestly, not everyone is this way, so saying "we" is just a way to be nice and include everybody. That's not accurate though. Everyone isn't ultimately selfish and tunnel-visioned. A lot of questions in this post. Hopefully they are challenging questions. How often do you not consider the other person? It doesn't matter who the other person is, stranger or loved-one. Do you consider them as legitimate human beings with as much right to live and move and have being as YOU?
If you find yourself often doing only your thing for you, others be damned, or not, whatever, you mean there are other people?? If you examine yourself and find that your M.O. is often you first or you alone - more that you just consider others a bother or not as legitimate as yourself, "in your way" in some way - then this is a big deal. I hate to bring the bad news but if this is the case, you are deeply broken in a very serious way. This is not little "oh well, do better next time" kind of stuff. It's major surgery time - like heart bypass kind of surgery time. Maybe you're not killing people in back alleys, but let's not pretend it's not high-order brokenness that needs some serious fixin'.
