Life is a difficult mess. There are far too many variables for any one human to ever grasp which can make life both controllable and enjoyable. I'm perpetually amazed that various people suggest they've got life under their thrall, an idea that astounds my belief glands into catatonia. Then again, we are living in the age of "alternative facts", and nobody is calling out this concept or the idiots who are perpetrating such madness.
Yet I'm not posting this to say unpleasant things about the obliviously obtuse Trump administration. They do a good enough job on their own.
All I'm here to say is that life doesn't need to be complicated. We just need to find a space that makes us comfortable, while not encroaching on the comfort space of others, and understand what we can, when we can. We are born, grow up, get old (hopefully), then die. There's not a load of time in between our start and end dates to fiddle with a ton of details that will forever remain out of our control. To try is just madness.
So, as the world's most accomplished gentlemen loser and general gadabout, I can only give you one small piece of advice.
