Unfortunately, Despite Obviously Being a Math Expert, “How Long Is 10000 Hours? ” Isn’t a Math Question. Instead, It’s a Question of How Much Effort You Have to Put into Mastering Something, Anything. So I Have a Much Better Answer to the Question…

What Is “Mastery”?

This Has to Be the Real Reason Why You’re Here. No Doubt, You Have Something or Many Things in Your Life That You Would Like to Master. We All Do. but What Does It Mean to Master Something?

Why Don’t We Start with a Dictionary Definition?

The Oxford Dictionary Defines the Word Master as Quite Simply:

A Lot of Research Goes on to Try to Figure out the Best and Quickest Ways to Learn. and That Makes Sense. in Our Modern World Filled with an Abundance of Technologies and Global Communications, Modern People Have to Know More Than Anyone in the Past Ever Did.

Author Malcolm Gladwell

In 2008, Pop Science Writer Malcolm Gladwell Published a Book Called Outliers: the Story of Success. in It, He Examined How and Why Certain People Succeed and Indeed Excel in Their Fields. and One Thing He References to Support His Ideas Is the 10,000-Hour Rule.

10,000 Hours of Deliberate Practice

It’s Very Important to Focus on the Word “Deliberate” Here. in Gladwell’s Outliers, He States That 10,000 Is a Magical Number of Practice Hours That Can More or Less Set Anyone Apart from the Competition. However, the Original Researchers Stressed That This Practice Has to Be “Deliberate” and Controlled, and in Most Cases, Led by an Experienced Teacher.

Focused and Directed…

Instead, Your Piano Practice Should Be Focused and Directed. You Need to Work Through Progressively Harder and Harder Songs That Push Your Limits. You Need to Fail and Try Again and Fail Some More Before You Learn Mastery. a Great Teacher Is Usually Necessary to Lead You Down This Path, Even If the Majority of the Practice Hours Are Done on Your Own.

More Factors Will Make You Better or Worse at Something Than Others. No Matter How Good You Are at Basketball, Someone Who Is Equally Good but a Foot Taller Than You Will Always Have an Advantage. but in Terms of Producing Your Personal Best Results, Putting in the Work Is What It’s All About.

Let’s Go Back and Break Down the Math of 10,000 a Little Bit More Reasonably…

Yes, 10,000 Hours Is Only 1.14 Year's, but You Have to Sleep, Eat, Shower, and Do a Whole Lot of Other Things in Your Daily Life, Too. So, What Is More Realistic in Terms of Reaching a 10,000-Hour Target?

If That Sounds Like Bad News, Remember Everyone Else Has to Put in 10 Year's, Too!

Of Course, There Are Exceptions Like Child Prodigies or People Who Can Work Full-Time (And in Their Spare Time) on Their Chosen Target. They May Reach Mastery Sooner Than You or I, but That Doesn’t Mean Their Mastery Will Be Better.

The Truth Is That 10,000 Is Just a Rough Estimation of How Much Work You Have to Put in to Achieve Mastery of Just About Anything. Putting in That Much Time Usually Takes Year's. and Once You’ve Put the Work In, You’ll Probably Use Your Mastery for Many Year's to Come, If Not for the Rest of Your Life.
