- A few small habitual tasks. – listing music and running or cleaning home etc.
- A task that needs most of our focus, as well as, a habitual task. – listening to a podcast or audiobook while doing maintenance tasks, or playing a simple, repetitive video game on a phone while listening to an audiobook.
Except these we should never try to multitask. Then we only switch task rapidly which creates attention residue, for that it takes 50% more time for the next task.
