I bought a ticket (the $1 kind) a few days after my 18th birthday. I pretty much said if Hashem wants me to win, it might as well be now.
If I won, I would not spend the money all at once. I would limit myself to using 150,000 a year… This way I wouldn’t go “sick with new-found wealth.”
If I won, I would pay off all mortgages and debts of my family, open up my own BY, start a Yeshiva in a small Torah community, give tzedakah – especially to people in E’Y, invest and save it. I would still work – although not as much.
