How to turn into a millionaire?

I'm really curious, how does one turn into a millionaire? Is it just a matter of luck or is there some kind of secret formula? I've heard stories of people investing in stocks or cryptocurrency and suddenly becoming incredibly wealthy. But is it really that simple? Or is there more to it than meets the eye? I'm not looking for a get-rich-quick scheme, but I'm definitely interested in learning more about the path to financial freedom. Could you please share some insights or strategies that might help me on my journey to becoming a millionaire?
