After a couple of scares, I worked out, how not to lose my stylus.

When ever possible use a finger nail, if I am doing something intensive away from my desktop and really need it, when I have it in my fingers, I do not put it down when I have finished using it, ie if I want to type on the keyboard, I keep it between my fingers then when I have finished what ever I am doing, I stow it back were it belongs in its convenient slot. The habit to attain is :- slot to fingers then back to slot, what ever you do do not put it down.

Remember slot fingers slot.

The art of the well lived life, is the cultivation of good habits and the losing of bad habits.
