A TED talked I watched a long time ago by Dan Gilbert made one point that I really enjoyed and has helped me keep perspective on things. And that is “if it happened over three months ago, with only a few exceptions, it has no impact whatsoever on your happiness.”.
That means that whatever happens today. Probably won’t matter in the long run. The only thing that matters is my perception of it. How I choose to react, how I choose to be.
“The great source of both the misery and disorders of human life seems to arise from overrating the difference between one permanent situation and another — Some of these situations may, no doubt, deserve to be preferred to others, but none of them can deserve to be pursued with that passionate ardor which drives us to violate the rules either of prudence or of justice, or to corrupt the future tranquility of our minds, either by shame from the remembrance of our own folly, or by remorse for the horror of our own injustice.” – Adam Smith
