This is probably one of the best descriptions on how to tighten by feel. The adjuster nut, a few fingers tight.

I use torque wrenches like other have state. Usually on fasteners that hold things together and not on spark plugs.
I do use the human torque wrench settings on the ratchet handle. Full fist for large bolts, thumb w/index & middle finger for mid size and thumb w/index finger for small bolts. YMMV. No full arm strength except on the large ones and what they're tightening on.
Takes some practice and pay attention on the last 1/4 turn of the bolt etc."
