You wouldn't think someone could write an article about a simple automatic function, the Tasks/To Do, would you? I am, because I'd like to extol the virtues of using your 'To Do / Tasks functions of your email / smartphone software.
Why? Because with a bit of clever thinking this function can take you from being good at sales; good at customer service; good at business development / relationship management to being utterly spectacular.
We all have a 'To Do' list. Most maintain it mentally. Some write down a list, or have 17 half crossed out lists scattered. You might use your software calendar to prompt you. Wrong place. The calendar is built for appointments and meetings only. Reminders make you look unnaturally busy.
Only a minority use their Task function, but even then only as a short term reminder system.
Let's look at it another way. For long term persistency. Tenacity.
