When you watch movies, you’re just seeing a series of still pictures. Why does it seem like smooth motion? Because the eye “holds” the image for a bit after it goes off – ‘persistence of vision’, so it’s called. But it doesn’t hold it too long (if it did, you’d see a mesh of all the different pictures).
We should learn to do the same in life, I think. To look at the past, just long enough to learn from it and make a ‘smooth’ transition to today. And to let go of it once you’re don’t need to hold on to it anymore.
Easier said than done, I know. But I think it would help in your journey through life. What do you think?
