My gramps was a wealthy man, when I moved to Venezuela he retired from his main jobs, to live of his rents, he was confident he will be able to live of that and have a hobby on the big farm he had.
Well, after a few years with the inflation that Venezuela had, it was impossible for everybody to live off his rents, so he decided to start working again.
When I asked why did he come out of retirement, he explained me that but he also said to me: “Watch me grow rich…again”
