It took me three tries to fix the wax gasket under my toilet (symptom of a worn-out wax gasket: water leaks out from the bottom of the toilet whenever you flush), but I did it out of curiosity, wanting to be more like my dad who fixed everything in our house, and because I didn't want to be the guy who called the landlord to fix every little thing... I think more than anything, the feeling of control over my surroundings is what pushes me to do as much handywork as I can.
