Memory is a tricky thing. In general, we forget about the bad, and tend to hold on to the good.
One upshot of this is our pasts can tend towards being better than our present. Though, in reality, the past really may have stunk. We just don’t remember really well.
Nostalgia is reflective of this attitude. In movies, decore, and people (instagram, vintage clothes, and hairstyle).
Myself included, of course, or I wouldn’t have noticed it in the first place. So as I focus inward, I just need to remember that my today beats the heck out of any yesterday. And of course, any tomorrow, as well.
