Habits are tough to shake and none more so when you become comfortable with what you are doing. I’m sure you are reading this thinking “What habits?” Believe me we all have them. I suffer from an allergy so sometimes if I don’t use a spray I sniff constantly and sometimes even if there is nothing to sniff, I sniff! You may not pick you nose but I bet sometimes you scratch it, even when you don’t know you are doing it. Any scratch in my book is a pick, from a distance. Itchy are we? Better scratch that itch after all we all have them? Don’t you dare I’m not shaking ands with someone I’ve just seen inadvertently scratching their backside, frontside or nose.
If in doubt hold something relevant, hold the lectern, hold your hands together but whatever you do don’t let them wander because they will without you even knowing it.
