Walking instead of using any kind of transport is much better, I can say this from experience. I used to walk 10 km every single day to my school when I was younger, just because I liked, and I was saving around $5 every single week because of that.

Even tho I finished school, I still go to a city nearby to drink some coffee with a friend, and while I could take a buss or something, I choose to walk, and not only I'm saving some money, but walking keeps me healthy and in shape.

I recommend that to everyone. Great post, and good luck in the future :)
