A popular wealth leverage model, both inspiring and down-to-earth, but also clearly simplifies reality:

1) Many people don't climb step-by-step from level 1 upward, but instead find their strengths and directly jump into levels 3-5 (for example, programmers transitioning to paid knowledge content, brick-and-mortar store owners switching to live streaming). Some people even run very large businesses at level 3 (top e-commerce sellers).
2) The bottom layer is "hard but stable," the higher levels are "possibly getting rich overnight, or losing everything overnight."
Not everyone needs to climb upward. Earning 300,000 to 500k yuan annually, being more free, and having a happy family is already very satisfying at levels 2-4. Forcing oneself to push upward can actually lead to burnout.
3) First, sharpen your skills enough and stabilize your cash flow, then consider leverage like traffic and systems. Many young people, after seeing this kind of diagram, go all-in on selling courses or traffic, but their fundamental skills are weak, and they quickly fail.
Overall, this diagram clearly explains the essence of the business world: making money is fundamentally about constantly exchanging "limited personal time" for things that are "reproducible, scalable, trustworthy, and financializable." It provides ordinary people with a clear "map," showing which direction offers the most leverage, but whether you can climb up ultimately depends on execution, learning ability, luck, and the timing window.
