This sounds too gimmicky and motivational. You need to be good at something that pays. I am not sure you need to be a cheetah specifically. Then you need to spend less than you make. I feel like this style of article is actually not conducive to that. Spending less is usually not flashy.

Basically you would do what FIRE people do, except you won't quit if your goal is wealth. In fact fire forums occasionally get a post like "hey I'm 61 I have 10m do you think I can retire?"
