When I was 18, I learned the Rule of 72. It is mainly applied when making investing decisions, but it has broad implications for speakers and general self improvement.

The Rule of 72 states:

Divide 72 by your interest rate and that will tell you how many years it takes for your money to double.

72 / 6% = Your money will double every 12 years

I know this is a speaking blog, but hang with me.

If you and I improve in an area of our life by just 2.5% a day, we will be twice as good in 29 days. (72 / 2.5% = 29)

Today, could you:

  • Be 2.5% more positive?
  • Be 2.5% more efficient?
  • Be 2.5% more loving?
  • Be 2.5% more disciplined?
  • Watch 2.5% less TV?
  • Spend 2.5% more time with your family?

Sure you can. Grow by 2.5% every day and in 29 days you will have improved by 100%

Same applies to public speaking.

With every speech if we are just:

  • 5% better with our vocal variety
  • 5% better with our pauses
  • 5% better with making eye contact
  • etc…

Then after 15 speaking engagements we will be twice as good as we are now. We will have improved our public speaking skills by 100%

Have some fun with the rule of 72.

Small changes done consistently over time create massive results. Learn more about this concept in  The Compound Effect (aff Link)
