Reading all this it made me think about what I have done and are currently up to now.
In short, I normally answer "I have done all except Preaching, teaching and skydiving."
Computer wise:
Started programming on the Sinclair ZX and Commodore 64. Bought my first PC (Olivetti) with only TWO floppy drives (no Hard drive yet) and started with dBaseIII. Then on to Clipper Alaska XBase++ then C++ (Borland products) and now B4A for Tablets and Raspberry Pi. Just started B4J for my next desktop app that will be closely integrated with scales and other processing equipment. (I am actually a mechanical engineer with a trade as well and a self taught programmed/systems developer.)
Software developed for the timber industry (From prep before tree plant right up to the lumber sales at the shop.) Then started developing Ready Mix automation systems and now design and manufacture our own PLC and use the Pi with Android Things.
AND, I don't care about money as long as I can ride my motorcycle on as many trips as possible. Maybe I am just lucky that I do what I like most and dont care about the rest.
Live once, die once.
