answer:10 – 7 is the best I’ve found if you’re going somewhere to work in a city. You miss the worst of rush hour on each side, can do a few things in the morning and don’t have to wake up super early, and then still home in time to enjoy your evening. Few businesses really support it, and if you have kids it’s tough, but it’s how I like to work if I can. Days of the week don’t really matter much except for connecting with others.
