Think about what you do during the course of a day and what you need to do it. Then consider any unusual activities you will be engaging in while away and what you will need for that -- this should help you remember most of what you need to pack.
I usually start making lists ahead of time, long before I can start packing.
the evening and morning of departure, put everything you use in the bag unless it is to be deliberately left behind.
