What have you learned from personal experience that goes against conventional wisdom?
For example (I'll start): I have found that "using the weight of the razor to do the work" doesn't really fit in very well with my technique. In fact, it doesn't really make sense to me as you can only do that when shaving downwards or across on certain parts of your face. Shaving upwards, the weight of the razor is working against you. If you have a really heavy razor, the weight of the razor might be too much pressure.
Instead, I accommodate the weight of the razor when holding it to my skin. A heavy razor has more inertia, which definitely helps it in its work, but it's not the weight of the razor doing the work. That comes from the motion of the razor as I move it across my face.
