The science of making money is already solved
The “science” of making money has been figured out for a long time. In short, the money-making machine is:
1. Work
2. Save
3. Invest
The playbook for building wealth long-term is stupidly simple: it pretty much guarantees you’ll retire a millionaire, even if you spend your life mopping floors.
How do you speed it up and get there sooner?
✦ Find a better job (↑ Work)
✦ Move out of Spain (↑ Work)
✦ Do side projects (↑ Work)
✦ Be more frugal (↑ Save)
✦ Move to a country with a lower cost of living (↑ Save)
✦ Learn to invest in individual stocks (↑ Invest)
Of course, just because it’s simple doesn’t mean it’s easy.
