Sometimes I like to read or do homework or just scroll on my phone while I commute but today I just feel like looking out the train. It's a really nice today today, very sunny, and I love watching how the sunlight hits the buildings and trees as I pass through.
I always find that long train rides are the opportune moment to refresh the brain and lock in. Think, you're sitting there with nothing else to do but work while also having momentary breaks to enjoy the scenery. If I can't bring my laptop, I use train journeys as a way to clear my camera roll and de-clutter my phone. Don't knock it til you try it
This is a type of walk I do almost every day. Walk in one direction until you hit a stoplight. Then immediately turn and walk in the new direction until you hit a stoplight and repeat until you get back home.
