The 80/20 rule has been a guiding principle of mine for many years.

It often gets interpreted as ‘80% I’m really good with my food and 20% of the time I eat what I want’, but the true meaning is far more powerful.

It’s about leverage

80% of your results come from 20% of your activities.

80% of your revenue comes from 20% of your customers.

20% of the carpet in your home gets 80% of the wear.

You wear 20% of the clothes in your wardrobe 80% of the time…

The mathematician in me loves this stuff!


Of course the numbers aren’t precise, but it’s a great model for keeping your focus on the ‘big levers’, and what’s most important.

Women’s Running Magazine article

I thought of this principle this morning as I read an article in Women’s Running magazine on how you can train for a marathon on ‘without much running’ that I was delighted to have contributed to.

Big goals like running a marathon can often seem like they’re going to require too much time or effort to even contemplate attempting.

So you put it off until you have more time (!)

But it’s often possible to get 80% of the result – in this case running the distance a little slower – with only a fraction of the input you may think it requires.

80% of something is better than 100% of nothing.
