Past is only useful as information, as a lesson.
Past, psychologically, is an illusion. You no longer are in the past. The “past-you” doesn’t exist.
If anything, the “past-you” and “future-you” are nothing but founts of pain.
Therefore we learn to “let go” of the past. To “be in the moment”.
Do let go of the past,
But if you DO get nostalgic… USE it now.
Use nostalgia today, to:
-to REMEMBER some of the things you once loved
-to REMEMBER some of the things which once inspired you, which you once wanted to do
Then DO those things.
This is how you use “nostalgia”,
To inspire TODAY.
It will also make you grateful.
Don’t use nostalgia as mere INDULGENCE with a feeling,
Use nostalgia to LIVE today, to take action today.
