My son!
My son! Devote thy mind to thy children as I did to thee, be tender to them as I was tender, instruct them as I instructed, keep them as I kept thee.
— from The Air Traffic Controller (God)
In the book
Ponder every word before you let it leave you, because once it is said it cannot be recalled, and carry yourself always as one who wishes to learn the truth, never as one whose only aim is to win the argument. Devote your mind to your own children as I have devoted mine to you. And do this above all: command your children to command their children in turn, so that the way of the Lord is carried on to the very end of all the generations. — The Air Traffic Controller (God)
Praise their effort and strategy rather than their cleverness, which raises a child who reaches for challenges instead of fearing them; and let them choose, because children free to pick their own interests are far likelier to find a lasting passion than those handed a track to run. The oldest ethical wills put the whole of it most tenderly: devote your mind to your children as I did to you; be tender to them as I was tender; instruct them as I instructed; keep them as I kept you. Protect — but not too much. This is the subtlest of the three. — Family & Parenting (Family/Parenting)
