A true revelation, it seems to me, will only emerge from stubborn concentration on a solitary problem.
I am not in league with inventors or adventurers, nor with travelers to exotic destinations. The surest -also the quickest- way to awake the sense of wonder in ourselves is to look intently, undeterred, at a single object. Suddenly, miraculously, it will reveal itself as something we have never seen before.
— Cesare Pavese (1947)
Inevitably, each of the things you do will suffer from the other things you do at the same time. The only way to achieve the maximum potential of anything is to completely focus on it. Quitting everything else.
