Depends on the people. If you want to be safe to retire early, it is a good idea to keep living humbly while you are making a lot of mone and not adopt the Jet Set life.
I've seen example of people selling their company, retiring early and stay low-mid budget. One particular example is very wealthy but live in a small house, drive a 10y old compact hatchback car. You wouldn't know his fortune just by looking at his habits. He enjoy more a BBQ with his neighbors than going to expensive places to eat and help around when someone in the village needs an additional hand. He is still probably spending a lot more than I do traveling on holidays and he has nicer furnitures but he is still doing it like most people do, only a few weeks a year when the kids are out of school. What he has is the ability to justify buying expensive but sturdy stuff that last, instead of things that break and have to be replaced on a regular basis.
