I literally thought that to myself a little over 3 years ago. Yes, literally thought about the marshmallow experiment in the context of my life.
You see, I came within a gnat's eyelash of having the classic widow-maker heart attack -- on the doctor's treadmill. (I didn't. I have no heart damage -- I'm fine, and lucky...) But I did spend a 3 day weekend in the cardiac unit getting a stent put in, and had the opportunity to think about 50 years of life choices. I spent half a century being a 3-sigma gratification delayer. Now, that has had a lot of positive impact on my life, but I also came to the conclusion that it was time that I started eating more marshmallows. (Metaphorically -- literally I eat fewer marshmallows because I am much more careful about my diet...)
So I would not go so far as to say: "Life is short, eat desert first.", but... I will say: "Life is short, don't forget to eat desert in moderation as you go along."
