When feeling glum, it sometimes helps to make lists of nice things. Of course it doesn't always work, (sometimes I just end up feeling greedy or poor) but I tend to do it anyway.
Nice things lately: belgian chocolate cupcakes, learning to bind books, big comfy dresses (which is great because it allows you to run when you are about to miss the train/bus/start of class), sunshine in the park with friends (not pictured) and the general feeling that cosy Autumn days are just around the corner. :)
