I'm really feeling the winter doldrums too though fortunately this winter snow has been a relative rarity here. But I'm getting tired of the cold. Getting grumpy enough to not want to ride but then I considered alternatives and decided I didn't like them either, except maybe just stay home and hibernate (not an option sadly )

Here are two ideas:
- switch up your route for variety. Take a longer route home to go by a good coffee shop / pastry place / whatever suits your fancy.
- treat yourself to some nice new merino wool to keep you extra warm
- make yourself some good soup (enough for a week) and know you can have some hot soup at the end of your ride (whether you bring it in a thermos to school or warm it up when you get home)
