I would make a slightly different point: The best way to earn is to find people who are willing to trade with you in a way that is fair for both of you. For example, I've worked (as in full time paid) for companies where I was told "Do X and we will pay you $Y". Upon completion of X, there was no $Y. This is an example of unfair trading aka not keeping up their end of the deal. I've also worked, for very little or no pay, and done even better work and the people/companies I worked for did exactly what they said they were going to do. Everyone has a different value space. If you are young and your time is cheap and you have lots of energy, find someone who needs that and is willing to trade you (ideally explicitly) for that in return for whatever you desire. That could be money, status, knowledge, experience etc
