So basically, be wealthy. All of your solutions require money up front, except maybe #4 if you're skilled and lucky, and #8 but the cc rewards for day to day spending is like 1 or 2 bowls of raman.
Most advice and success stories are too vague, unreproducable, and/or obvious to be useful.
I understand some people need to be told not to spend $5000/year on coffee, but it's exhausting when I've never spent money on coffee in my entire life and 99% of personal finance advice is on that level of unhelpful.
