Hahaha, backwards selfies are the best selfies!
Where I've had to work in the city, I always cycle... I had being dependent on other people, whether it's the people in the cars of the traffic around me or the people running the public transport. Not relying on anyone else gives you that freedom to control exactly where you are and where you want to be... which also helps your mood. There's nothing worse than feeling trapped or out of control.
