Venture capitalists Marc Andreessen3 and David Skok4 both use a similar 10x rule in the growth models for their portfolio companies. Like a Fermi estimate, the 10x rule isn’t intended for significant precision but as a rough (yet good enough) ballpark. It works reasonably well for most products, but you should always check your own numbers to see i

In the long-run it is probably most effective to work on the strategy that seems to deliver the best results about 80 to 90 percent of the time and keep exploring with the remaining 10 to 20 percent. Google famously asks employees to spend 80 percent of the workweek on their official job and 20 percent on projects of their choice, which has led to

Is it exactly 20 percent? Not necessarily. But thinking of it as 20 percent is a good start. If we focus our attention on the top 20 percent of user traffic and ensure those items are first in line for any kind of enhancement or additions, we can make relatively small improvements that will yield disproportionately powerful results. In other words,

By contrast, 10x is so big and seemingly impossible that it immediately forces you out of your current mindset and approach. You can’t work 10x harder or longer. Brute force and linear methods won’t get you to 10x. 10x has become a trendy concept thrown around in entrepreneurial, financial, and self-help circles. Yet, most people radically misunder

Pareto's Law and can be summarized as follows: 80% of the outputs result from 20% of the inputs. If you take 10 of your tasks and activities you want to get done, two of them will produce more results than the other 8 combined. This is a proven fact.
