For me, it’s about the essentials.
Especially when it’s just as cold inside, as it is outside, make sure you have all you winter essentials: turtleneck, scarf, hat, lotion, lip balm & gloss, and sunnies for those bright chilly days!
I know, it’s easy to just keep throwing everything in your bag until soon you can’t find anything. Then you get a bag with all these pockets and you still can’t find anything because you can’t remember which pocket it’s in.
Why carry more than you need?
