Mine is licking my lips this was from childhood and know if I have a decision to make or a really busy, exhausting day I still do it. I am doing it far this often as I am more aware of it. It makes my lips really dry and sore even in the summer so I really need to stop doing it!
Mine is entering all my accounts onto MYOB (accounting package). I have been doing this since I had my own business, however do not really have a reason to do it anymore, but somehow cannot stop!
It has been suggested that I start an MYOB anonymous group!
I play with and twiddle my hair through stress, I remember doing it at creche when I was just 4. My mum tried to get me to stop it, but although I tried, I couldn't.
Though since having it cut shorter, means I play with it less anyway!
