You're certainly lucky to be able to walk to your office. Most people in my company need to drive at least 50 minutes to get to the office.
I lived 10 mins away on foot from my job. It was all fine and dandy for some time, but then things got seriously tense in the workplace and it meant the super short commute gave me no time to unwind. It ended up being mentally taxing to live so close to my workplace, even when I was not working since I ended up being near or walking in front basically anytime I got out. Nasty. Too long a commute and you're wasting so much time and energy in our life, but too close and it can have deleterious effects too.
