Not sure if this falls under it, guess it does, but years ago I worked for a small contractor and learned a lot from old Frans (his name). A man with few words but practical and handy as one rarely sees. Those days were great but he used to tease me and said that I was always way too theoretical, looking up every job (to do) in books and doing it in my unconventional way (hey, that's me) whereas he.... was practical to the bone and just did it. I learned by looking 'cos he rarely elaborated anything. Not always easy, at least 50% my bad, but cheers to you, Frans.
Do you consider yourself, 'good with your hands' or, lets say, quite handy?
