It's a bit swings and roundabouts I think.
I don't think there is anything wrong with your approach, but it suits a certain type of person. On the one hand, it's good to manage your money, but on the other hand you could be dead tomorrow.
As I mentioned in another thread, my dad died aged 44, about 8 days before his birthday. He'd never been anywhere except Ireland, Jersey and Norway. Since I met my wife we've been to Malaysia (twice), Disneyworld and associated attractions 4 times, Slovenia, Croatia, Italy, France, Mauritius, Portugal, Spain, Germany, Canada and have so many memories from our holidays, nice hotels, fun times with the kids etc.
I could have just been like my parents and gone to Wales or Devon every year. We'd have paid off the mortgage by now.
Personally I'd rather have had the holidays, the fun and the memories. You're only young once, and if you are unlucky you don't get to be old.
