Figuring out which tasks we should do next is not always an easy decision.
So instead of using your precious mental energy for decision making, let Marvin decide for you!
If this strategy is turned on, you will see a lightbulb icon at the top right of your daily list or any Smart List you have in your day view (via the custom sidebar or custom squares for example)
Clicking the icon pops up the task Marvin thinks you should do next.
He takes many factors into consideration, but his exact thought process is a secret. He will get smarter over time, giving you better and better suggestions.
If you just want to get a random task instead, use the random task strategy.
