I think I have way more tools than normal people.
Since I got my car I had to get more than one big box of stuff so I can change oil and braking fluids myself. Also soldering station, dremel, screws, cables, lots of woodworking tools.
I already threw away tons of electronics stuff since I didn't do any microcontroller stuff anymore since I left university.
Lots of people have their shit under the roof or in the cellar but I prefer to have it in my flat so I can easily fetch it whenever I need something.
