How many of these things can you do without assistance:
Add air to a tyre
Change oil
Change a wheel on your car
Fix a bike pucture
Put up shelving
Change a plug adhering to all safety advice and best practice
Put together a cabinet-size piece of flat pack furniture
Set up a home network
Diganose problem and mend toaster
Change element in an oven
Sort out a fuse box if lights go off
Turn off water at mains in case of leak
I can do none very confidently at the moment, but at a stretch might be able to do three.
I want to be able to do them all.
