I am a very forgetful person. To make sure I don't forget anything when we go on vacation, I list everything that we need weeks ahead. I always have a notebook inside my bag, in fact I have notebooks all over the house, so I can jot down reminders even when I am doing some errands. Even when I'm out of the house and I remember something that I need to bring on our vacation, I can update my list right then and there.
So thanks to my notebook, packing for vacation is a always a breeze. From my son's nebulizer to my moisturizer, camera and the hdmi cable (high-definition multimedia interface), clothes, and everything thata we need is in that luggage.
