If it works for you, it's worth trying. Maybe not so great to obviously have to pull out your crib notes for socializing, but if you feel overwhelmed, sneak off to a corner or into a bathroom and remind yourself of your strategies. Keep it simple though. Or why not try "practicing" each of the hints by taking one at a time, one day at work reminding yourself of ONE strategy and making conscious effort to apply it whenever you can until it becomes more natural.
Obviously cheat sheets are not the optimal strategy, and you want to work yourself to a stage where the techniques become second nature, but if bridging that gap is difficult, anything that can help you is worth the shot.
Just don't become too reliant on any aids - try to wean yourself off them quickly.
