Last time I had a regular job the 32 hours per week already felt way to much. It may comes from my burnout in the past but I really do not understand why so many people who would have the choice opt for working more than less. I don't think enjoying life when old (fire or rich pension plans) is a good plan either as it's not that likely to even get there without serious health issues (statistics, not because I'm unhealthy) and my today's money is worth nothing then when I would need it. Working little but smart, don't be wasteful with your money and invest smart is kinda what I try doing.
