A gift from my colleagues. ‘Tegeltjeswijsheid’ means ’tile-wisdom’ or the often somewhat cliché phrases that are printed on tiles as an old fashioned type of decoration. We moved into new offices this January (in the same building), and since then everyone of us is getting their own tile with some characteristic phrase etc. about them. Yesterday I received mine. It reads “In my notes of 20 years ago I see that…”. A (exaggerated! really!) reference to my personal knowledge management (pkm) system. I indeed regularly inject things into conversations, when some question or topic is discussed along the lines of “last time we discussed this in 201x, we thought this or that, and concluded somesuch”.
