Investing is not about giving money and expecting to have more money.
This capitalist investment.
Investing is about giving resource and expecting more.
Time is the most precious resource you have.
Unfortunately, you can't expect more than what you are given.
Investing time for money is a smart move, until you earn more than what you need to live.
Investing more than what you need is what economist call waste.
So now you have enough money, where to invest your time ?
In my case, I found that having guts to test new things and leaving the comfort zone without any fear of loss, is something that make every second of my time worthwhile and fun.
Investing in curiosity is definitively a good move.
