But Marc, seriously, is it really frugal to buy a book for CHF 59, or even CHF 249?!?

As usual, my answer is: how much value do you expect to get out of it?
If you’re going to buy it, read it, and carry on with your routine without changing anything, then clearly, it’s not a frugal decision.
If it’s your concrete plan to buy it and apply my step-by-step methodology, then the return on investment you will get will be with many zeros. Why? Because if you start from point A (novice) and get to point Z (expert), you will be hundreds of thousands of CHF richer when you reach early retirement.

As for me, if I had been offered this step-by-step guide in 2013, telling me that it would allow me to reach CHF 540'000 of net worth six years later, instead of staying with my CHF 50'000… my answer would have been clearly “Where can I buy it?!?"
