Wise words that made me engage my grey matter.

So there is a difference between "success" (or failure) and "perceived success" (or failure).

I have been a tinkerer all my life. The goals of all my hobby projects have always been the joy of doing it and the learning experience. From my point of view, very few of them failed to achieve those goals. But for first my parents and now my spouse none of them achieved anything as I never made any money on them.
