Practice deliberately

Flow depends on having at least enough mastery over your skills to understand when things are going well and be able to adjust on the fly when they’re not. But repeating the same task gets monotonous and make us more prone to small errors, leaving us unable to push and develop our skills and find Flow in the process.

To counter that, take an activity you do regularly, break it down into segments and go through each segment systematically, always looking for ways to get better.
