If you find your time in the afternoon isn't productive but you find it fulfilling to be around the people you love and that's enough for you, then you don't need productivity advice and this kind of reading isn't for you.
If you are tired from the moment you wake up to the moment you go to bed again, you’re suffering from depression or an incredibly bad diet, go see a nutritionist.
And I said the opposite of ‘’[we] spend too much energy on things we’d rather not spend’’ - if you’re already spending time on things you love to do like being with your family and you just want to do more in the limited time you have, either carve the time out of one of those things you love to focus on something else, or learn to accept there’s only so many hours in the day.
