a new experiment this year; just use paper cash money. The rationale is this: one of the most successful people that I met, one of my students at one of my workshops, who lived in Beverly Hills, and I still remember… I was because he showed up to the workshop with just a basic Olympus camera, even though he could probably afford 1 billion Leicas.

Also — what is super interesting is that he told me one of the best pieces for everything, besides, which is almost impossible to pay in cash.

Also when you have the option, maybe is better to just use a debit card. Not a credit card.
