- I can control to enjoy a scenery or a picnic from local park or nearby forest and
- I can control of being worried about the money and doing exactly what I feel like doing (considering it makes me trully happy)
As a rich guy:
- I'd not be sure why I should pedal and sit on a muddy grass instead of renting Hummer and going to some fine dining restaurant
- I'd not be sure should I be wasting my time having all this money when I could be treating myself with X and Y
Once again, what's the benefit if I need to take a mental and physical effort in order to be happy? Your last two paragraphs are the exact thing I am talking about, and can be applied to non-rich people as well.
