I like to wear my mask very very very low on my forehead... so low, in fact that it covers my eyes and nose. This is the most comfortable and safest position and I can easily reposition it for diving with zero hands. No one has ever asked me if I was in distress, because I remain calm at all times.
When shore diving, I install my mask in dive position when I step away from my truck and then remove it when I return to the truck. For boat diving, I put it on when I stand up to walk to the stepping off point and remove it after I have sat back down on the boat and removed my tanks. Never lost a mask.
