The best way to make money is by providing value that will benefits others.
This is one reason why most get-rich-quick schemes fail. They provide zero value.
When you provide something that people want or need, money usually follows. Sometimes it happens before you even realizing it.
The more people benefit from the value that you provide, the more money you will gain.
A great example would be you-tubers who make million dollar out of making videos. A lot of them started out making video just for fun not for money. They keep making video about their passion or hobbies or whatever. Little did they know, their videos somehow provides such great value that more and more people subscribe to their channels. Eventually, money start pouring in from their YouTube channel.
Another great example would be writing on Quora. Some writers started out answering people question, because they think it’s fun. They didn’t realize that their answers help people so much that people on Quora start asking them personally for advises on their areas of expertise. Before they know it, big companies want them to be their consultants.
Same goes for all other people who are already rich and making a lot of money (not counting lottery winners). They all provide something valuable to help or improve other people’s lives.
