To me, it is to have enough money, so I can do what I want, when I want even that doesnt mean owning an private jet and spend millions on holidays. It means being secure, and being able to live and healthy and sustainable life. Also be able to change plans and location when you feel enough is enough. Thats happiness. Having a meal with good friends, is great, but just a temporary feeling of comfort.
A good lifepartner comes high up on my list, but economic secured comes first
