100 hours of football practise. Not using the 80/20 rule, the footballer divides his time evenly to the different tasks.
Using the 80/20 rule, he spends more of his 100 hours on the things that a) impact the results most, and b) he needs to improve most.
a) could be, as a simple example, goal scoring accuracy.
b) can be anything that is a weakness.
Doing this, his pie chart of time distribution would look different, but still be filled with 100 hours. However, in many many cases, this more effective use of time would result in not needing to spend the entire 100 hours. Why? because he would have improved more on the things he needed to improve more on, much faster, because he spent more time on them on a shorter number of sessions (of 100 hours), in place of the same amount of time that he spent on one session spread over 3, for example.
