how can i get rich?

Invest what you can in the stockmarket.

There are what a few people I know call "Blue Chip" stocks which are Apple, AirBNB, Tesla, or Amazon for example. They have a great deal of high return. I've made great money from AirBNB and Marathon Progressive Research Group (a bitmining company) and have been able to grow my initial investments to the point where I can work directly off of gains. It isn't cash heavy rich until I sell, but asset rich is also a grat position to be in.

If you can also invest in fine art early on, and sell when you need is a great option.
