You have to have enough respect for other human beings to leave their lives alone. If you admire that life build it for yourself. Don't just try to come in and take somebody else's life.
There are no college courses to build up self-esteem or high school or elementary school. If you don't get those values at a early age nurtured in your home you don't get them.
A truly great book should be read in youth again in maturity and once more in old age as a fine building should be seen by morning light at noon and by moonlight.
Believe me that was a happy age before the days of architects before the days of builders.
The answer to old age is to keep one's mind busy and to go on with one's life as if it were interminable. I always admired Chekhov for building a new house when he was dying of tuberculosis.
