If you're running a SaaS, presumably it's cloud based. Why the 50 min commute?
50 min each way is 100 min per day, 500 min per week. That's an entire work day.
A commute that long isn't for founders, it's for wage slaves!
Before we got the office I did 6 months from home and I was highly ineffective. Remote work is just not for me.
The commute itself is rather pleasant and I can work on the train if I wish, although I mostly use the time to read HN and relax.
