Making money doesn’t necessarily imply value is being created. For example casinos create the illusion of value and generate a lot of money.
Unfortunately, like a casino a lot of tech is an illusion, e.g. social media- you walk in and it’s flashy and exciting, but you walk out having lost hours of your time and possibly a few brain cells.
If you solve valuable problems you will make money.
If you have a side project then spend all your time solving valuable problems not posting about $$
