I use the Inbox version of Gmail. And I’m a big fan. Seeing that partly cloudy Sun image bring a smile to my face.
When that Sun shows up, I know that I’ve hit zero emails. It forces me to either respond to emails or get them out of sight and move on to more high value work.
I’m a big proponent of forcing discipline on myself. It’s a motivating force to put myself into situations where I know I can be successful.
It’s a simple thing, but batching my email responses and keeping that zero inbox make me feel accomplished to a certain degree.
