Glad it works for you!
Inbox zero is a cognitive hack in a way that works for some (at least for me). It frees some of the mind-cycles that normally are wasted on worrying about an ill-defined and always growing 'todo list' held in a mail account. I personally prefer to define my tasks, at least the longer ones, using verbs - as I would delegate them, but to myself. Also having more clear outcomes defined and written so I don't have to think about it more than once helps me a lot. So if you are like me, having inbox zero and a clearly defined todo list just gives more freedom to be creative and focused on a task at hand and not to worry unconsciously about everything else waiting in my mail account. But everyone's different so what works for one doesn't necessarily work for others and everyone can or maybe should pursue their own methods to deal with 'stuff'.
