Productivity coach Hillary Rettig suggests that you should leave early as it empowers you. According to her, "When people are commuting, they're most likely rushing," This creates all the stress and lowers your happiness. So, spare enough time by doing things well beforehand, and commutes will become peaceful and happy.
Very much possible for those who take a train or a bus and then walk down to the workplace. Choose a different route after a few days, or walk down the beautiful lanes of your city. You can sure find joy in the little things a city wakes up to every morning. Find out new shops or the never-before-seen details of an undiscovered city space.
Look around you and get inspired by your surroundings. It could even be people commuting with you in the train, kids walking to school, a vendor getting his shop ready for the market, and so on... There are so many things around you that can give you great ideas about trends, or you can simply learn so much about people, about this wonderful world.
When you know you are still 35 minutes away from your destination, it is not at all a bad idea to take a good nap. Just make sure, you wake up at the right time - either set an alarm, or know someone who will definitely come to your aid here. Sleep is definitely a productive restoration activity, more so on your way back home.
