HOW TO LIVE ON 24 HOURS A DAY by ARNOLD BENETTMy rating: 5 of 5 stars
This short book teached me few things that maybe other larger books couldn't teach.
1. I knew that among all the life variables, time can't be recovered. Money, happiness, or even health can be recovered, but the spent time cannot. But here I learned that also time cannot be spend further. You can't waste a week or a month once as you can spend your income on a bet. You can't spend your next day today, nor next hour now. And that's a good news, cause time it's well kept resource.
