Lifestyle definitely.
Money cannot buy you time nor happiness, but it did pay for a load of flying for me. The only problem was trying to fit the flying in around the very little spare time I had.
Still came to my senses and went back to a nice cosy office job 9-5, taking a several thousand pounds pay drop. Yes I admit I miss the money, but I'm much happier with a load of free time to do with as I please.
I find that 'rich' people are the ones that are always unhappy. Since they've bought everything they ever wanted, they still have something missing, which they can never pinpoint nor can they buy.
