The 80 20 rule is one of the most helpful concepts for life and time management.
Also known as the Pareto Principle, this rule suggests that 20 percent of your activities will account for 80 percent of your results.
If you have a list of ten items to accomplish, two of those items will turn out to be worth more than the other eight items put together.
The sad fact is that most people procrastinate on the top 10 or 20 percent of items that are the most valuable and important, the “vital few,”
and busy themselves instead with the least important 80 percent, the “trivial many,” that contribute very little to their success.
