Thats true hard working people are always needed who can fix cars, build houses, grow foods, repair sanitation.... If you offer a great service people will always come back and you will have a great life.
But if you always work you wont have much time to think about finances. You will have to make your profession your dream. And then retire at 60 or 70 or never because you like it so much.
Some wise man said most people dont even think 5 minutes about their money, but it can make a huge difference. Most people do not even understand the concept of going early in promising projects... But thats how early btc and eth miners/investors got rich. Not by buying them when they were already high so something as KoinOS if you look at its market cap and their features like free smart contracts has a ton of potential and upside, kinda like buying eth and btc early but you can do it now still, so thats amazing.
And then you can fully "work" for fun with absolutely zero need to have an income still so you can start projects to benefit communities or try change the world for a better... even if just a little.
