you can save a pretty significant amount of money over time if you learn to walk faster (none of that leisurely pace shit). turn that 15 min walk into an 10 min one and you won’t feel the need to take the train as often. good luck!
If you’re within an hour walk from home, you should just walk home.
I understand taking public transit or an Uber there to be on time, but you’re not rushing to get home. Thus, walk.
