This article misses the entire point behind 80/20.

If I have 10 tasks on my to-do list, chances are 2-3 are far more effective and impactful than the others.

As such, I should double down on those tasks, and either outsource/eliminate/minimise the effort spent on the remaining tasks.

The same goes for marketing channels, customers I'm targeting, sales techniques, products I'm selling and so on. By not being clear about this, we spread ourselves thin, spend a disproportionate amount of time on low value activities, don't get the positive feedback loop we need to keep going, and ultimately burn ourselves out.

Effective people identify the signal in the noise, and devote their time and resources accordingly.
