My version of being productive was interrupted for 6 days when I misplaced (aka: lost) my trusted Moleskin Notebook.
I truly realized that my level of productivity is driven by my use of the processes I have honed over the years. Use the notebook to set a weekly Goals and daily tasks; block incoming messages when doing project work, delegate and follow up, etc.
Found my notebook today and feel good knowing I am back up to my productivity norms (and always working on improving.)
