I usually have to commute for 3 hours a day. I have to be up early and get home late, stuck on a crowded train normally standing up for most of the journey.
I was never previously a big fan of working from home, I enjoy the social interaction at the office. Having coffee breaks with people, going out for lunch etc. But now I'm used to WFH I love the fact that I can wake up at 9AM and I'm 'at work'. I finish at 5:30PM and I'm already home. Yes I do miss the interaction with people, but I have met some people outside work, and regularly have Slack convos (or social ones while gaming for example) with those people.
I feel lucky that I've been at my company for a relatively long time, so have 'work friends' who I continue talking to. I now don't talk to the 'acquaintances' or new starters for example, which I guess is sad - but being selfish, makes it feel like I have even more time to do my own things. But on the other hand, probably isn't so good for the newer members of staff and doesn't help company morale.
I am still fairly young and have seen some people mention work/life balance. That doesn't bother me too much either as my company is flexible and I know if I do a few extra hours one evening I can do a few less hours another day etc. and wouldn't have to tell or ask anyone to do that.
Until reading this post I hadn't really thought about it too much, but guess I am just lucky that it works for me. If I was older and had kids/family, or didn't have an office to work from at home I can see how it would be more of a struggle. I do want to go back to work at some point, but I don't know how often I'd want to be there. I don't know if I can handle the long commutes week in week out now.
