Who gets your help?
My mother always told me (not that I believed her), that you had to take care of yourself first because no one else would. I eventually, after many years and personal disasters later, reached the same conclusion, undoubtedly for similar reasons. Friends and mates can be a great support for those of us lucky enough to have them, but bottom line is you need to be proactive in caring for yourself. No one knows you better than you. No one knows what you need more than you. Finally, you have to take care of yourself because if you aren’t alive, you won’t be helping anybody.
Thus I work from the center out. I try to take care of me first. I’m better at it than I used to be, probably because I’ve had all these years of practice and because failing to do so could be lethal. At some point I realized this IS tomorrow. There’s no more waiting time. Everything needs to be taken care of now.
After that? My family and friends and if there’s any time, money, or energy left, the world. If I were to prioritize the list, “the world” would be first because I’m convinced if we fail to take care of this garden in which we live, there will be nowhere else to go. I don’t see us zipping around the galaxy looking for places to colonize. It’s a nice thought, but I don’t think it’s going to happen — and if it did, it would be too late for me and probably everyone else I know. You can bet if we were to colonize, they would pick young, well-educated, healthy, and smart people. I doubt very much that anyone I know would be on that list — for one reason or another.
So for me, if this is a real question, then we start with the most “propriate” (Definition: Of or relating to the self or proprium) and then move outward. Honestly, I think saving the world has become another generation’s problem. I hope they take it seriously and become involved.
I’d like to point out that my generation did NOT create the mess we are in. We are the group that tried, however ineffectively, to fix it. Go back a few hundred years to the Industrial Revolution. That’s when we began a campaign of fouling the air and water while simultaneously poisoning the soil. It didn’t start with your grandparents. It began many generations earlier and now, it has landed on you. Blaming other people for the mess only takes you to Facebook or Twitter. If you want to fix something, find a way to get involved. Do something useful. Or, at least, shut up about it.
