Lay out ONLY those things you think that you will NEED. Then go through them again and remove 1/2 of them. Look at the resulting items. Is it all something you absolutely can't travel without (ie meds, id, travellers checks, credit cards, toothpaste, clean undies) Keep these things and deep six the rest. All you will need is 1 pair of jeans, one shorts, several tops, one casual/dressy outfit i pair comfy walking shoes and one pair of casual dress shoes (also comfy). One jacket/sweater. If something becomes vital you can purchase it. Anything else is just extra baggage. HTH
