Seeing people saying, "It's me time." is a bit disconcerting. Respectfully as an opinion, spending between 2 and 4+ hours a day sitting on a bus/train is not "me time". Why do I think that? Because of what I suspect the answer to this question would be: If you had 2 free hours at home would you spend it doing the exact same task that you would do for 2 hours on a bus?
I understand that a two plus hour commute is a choice and obviously there are people willing to accept it. But I am suspicious that the "me time" argument is in reality a rationalization to make what would generally be unacceptable appear acceptable.
And as an appeal to the emotional side, you have one life. Do you really want to spend 10% of your life on a bus every month?
