In a world with so many distractions the one thing you cannot afford to lose focus of is your customer.
For the past three weeks I set a calendar reminder to alert me each morning to ignore things that do not help our customer. Each time this alert goes off it triggers:
1) a moment I spent with a customer - usually a moment where they were struggling with a product feature that we need to fix.
2) energizes me to do more of #1 so we can make our product even better.
3) reminds me to drop something I am currently working on.
