Today, I came across a book entitled The Spare-Time Book: A Practical Guide to Adventure.

The foreword was by Roger Bannister, who used his spare time training. He eventually became the first person to run a mile in under four minutes.

It was a helpful reminder to my judge aspect—my inner critic—that at some point, the authors and a publisher saw that the market needed to learn how to use their spare time more fruitfully.

With all of the thin rewards that we are presented with today, I think that’s more true than even before. You probably won’t be on your deathbed wishing you watched more TV.

But you already know this. What’s less clear is what you can do instead.
