Ellen Langer says that:
If you make the moment matter, it all matters.
Does he simply means?:
If the moment is important, every moment matters.

It’s going to sound corny, but I believe it fully: Life consists only of moments, nothing more than that. So if you make the moment matter, it all matters. You can be mindful, you can be mindless. You can win, you can lose. The worst case is to be mindless and lose. So when you’re doing anything, be mindful, notice new things, make it meaningful to you, and you’ll prosper.
