I was working way too hard in the late 90s, early 2000s. Then, a few events caused me to realize that life is short, and I should start enjoy it more, instead of deferring everything until I retired.
I had not been scrimping, but I indulged some more like foreign travel, buying a 2nd home. If I did not, I would have more money now, but the opportunities would have been lost, as I am older now and would not have the same pleasure as I did. And I could have been dead from an illness 3 years ago.
So, doing OMY to allow oneself a bit of leisure is worth it. YMMV.
