W. Somerset Maugham said this quote

“ It’s hard not to be impatient with the absurdity of the young; they tell us that two and two make four as though it had never occurred to us, and they’re disappointed if we can’t share their surprise when they have discovered that a hen lays an egg. There’s a lot of nonsense in their ranting and raving, but it’s not all nonsense. One ought to sympathize with them; one ought to do one’s best to understand. One has to remember how much has to be forgotten and how much has to be learnt when for the first time one faces life. It’s not very easy to give up one’s ideals, and the brute facts of every day are bitter pills to swallow. The spiritual conflicts of adolescence can be very severe and one can do little to resolve them. ”
