Where to start with this one? I guess most people's goal for 2021 would be just to get through it, to survive, to be there at the end ready for 2022, still standing. That's a reasonable enough aspiration and if your circumstances are tough then a fair one. In 2021 I'll turn 66, not a bad age to be, but one that comes with some questions, the normal wear and tear and baggage. I'll be an official pensioner then, so how should I behave or conduct myself, how do old age pensioners actually think? The same as everyone else I imagine, apart from the fact that you're a few years, days, minutes closer to the cliff edge that is your own mortality. Don't take risks, eat sensibly, don't break a hip etc. Or, drink, smoke and eat all you like, say what you like and don't give a fuck?
Apart from the continued confusion and human fallibility it's all probably going to be fine. I've garnered enough life experience to know that what I say and most of what I do doesn't really matter, it's already floating off into the cosmos and leading a reasonable little life of it's own. A silent echo of what was and what shall be. So, I'll be content to leave less mess, clear up as I go, try to be kind, try to listen, try not to bite when antagonized and avoid too much alcohol and spicy food ... and love as much as I can when I can. That's a good start.
So is there a difference between "goals" and "own goals"? Yes, own goals hurt a whole lot more and their impact and legacy last a whole lot longer. I know I'll score some own goals in 2021, I just hope that they don't make any real difference. It's scoring real goals that counts. In conclusion, just live your best life. The score you get will reflect that.
