The company that makes my skin care products makes travel size bottles - the amounts in those can last me weeks. Has greatly reduced how much space/weight is in my luggage/carry on.
Now, as a bigger girl and one prone to spilling food down the front of me, I still take too much clothes (and the clothes I do have take up more space than a skinnier person's), but I'm trying to pare that down too - both by losing weight and reducing how much I take.
Unfortunately, I'm still a card carrying member of overpackers not so anonymous.
