However, being Ealing, I also had the option of taking the District Line to rougly the same place (Tower Bridge). My journery was now 1hr 15m, however with the DL's spacious air-conditioned carriages and guaranteed seat, it was well worth it. It put me in the best state of mind and allowed me to use my laptop to work on my own projects. In 6 months of 2hrs to myself each day, I wrote medistudents.com and still was able to relax at the end of the day and not let software development impact home life. Without the commute and this opportunity to work on my own things, I would have either never found the time for a side project, or p*ssed off my girlfriend for spending all night on the laptop.
Nowadays I either work from home or commute by car. It's just not the same - either from looking at the same 4 walls every day, or regarding time spent in traffic as a complete waste. And my time on my own projects has now essentially reduced to zero.
So if you commute by a comfortable bus or train, spend your time wisely. Definitely don't waste it playing Candy Crush. Take advantage of it for working on a side project, learning something new, or just self-reflection.
