Do you have any items that you swear by when you are travelling, especially for business purposes?
I was talking to a colleague, and he mentioned that his wife takes a door jammer when she has to travel by herself. I thought that was pretty cool, and the thing is apparently really light.
Here's a few others I found on Quora that might be useful (via http://www.quora.com/What-are-your-b...-packing-hacks)
1. As soon as you arrive, hang shirts up in the bathroom. When showering or bathing, make sure you keep the door closed and the steam will help the creases to drop out.
2. I'm guilty of having used this on occasion: don't pack a cell phone charger. When you get to your hotel, walk up to the front desk and tell them you left your <insert common phone brand> charger there the last time you stayed with them - they will invariably find one in their massive drawer of left-behind chargers.
