The way I see it, having money would make life easier in some respects - won't have to worry about paying bills, the ability to buy things you want on a whim...
However, having money then brings a whole new lot of issues/problems/stresses - charities hitting you up for money, family hitting you up for money, getting trapped with "keeping up status/appearances", teaching your children the value of the dollar, learning how to manage your money wisely, etc.
Look at the stories of people who win lotteries that wind up even more poor than they were before they won. Why is that? Mostly because they spent the money rather than learned how to manage it wisely - and got caught with owing taxes on their winnings, buying things they didn't really need, etc.
If I came into a fortune, I probably wouldn't change much about my life. I like the house I have now - wouldn't want anything bigger as I wouldn't know what to do with the space. I'd probably buy a new hybrid car - but it would be an economical car, not some overpriced fancy one (not really a "car" person). I'd have an easier time fulfilling my wish to take my nieces/nephews on a special trip a year or two before they graduate high school. I'd probably invest the rest and would definitely increase my charity giving.
One of the best stories I heard was a former co-worker knew a man (retired) who won their state lottery years ago. He said he didn't change a thing - just invested it all. He still lived in his same house, drove his same 1970's car. Went fishing on the weekends. Most people had no idea he was "rich". He'd go to charity fund raisers to donate money to causes he'd believe in, but he wouldn't dress up in fancy tuxes - he'd come dressed in a nice flannel shirt/jeans/tennis shoes. When asked why, he said he was there to donate money, not to put on a fashion show. LOL.
