It takes a bit of motivation (but not a lot) to do some yoga from YouTube in the morning. These might just trick you into being in a good mood, but they seem to work for me. Everyday I do one or two yoga videos.
I pick out my clothes at night usually but if it has to be done in the morning I like to keep it simple. During the winter its really difficult because I've got to think in layers, but now its a breeze to pick a dress out of my closet and pair it with a light sweater.Showering at night gives me a lot more time in the morning, and then I let my hair air dry at night then fix it with the blowdryer in the morning. After that I put on my makeup and then I'm off to the train!
