I solved a Rubik’s cube for the first time last week. Naturally, I’m telling everyone. Nerd problems!

It took forever. I was putting in the time. Why couldn’t I solve it?

I finally succeeded two weeks after reading Cubed: The Puzzle of Us All.

Cubed is no solution guide. It’s the intriguing life story of the reclusive creator of one of the most ubiquitous puzzles of our time, and his story helped me realize I wasn’t spending my time productively. I was allocating the time, but my mind was elsewhere. I wasn’t successful until I spent dedicated time truly thinking about the problem.

Any task you deem worthwhile requires your time and your full attention.

Your time is finite – use it well.
