When you make a mistake,big or small,cherish it as it’s the most precious thing in the world.

Most of us feel bad when we make mistakes,beat ourselves up about it,feel like failures,and get mad at ourselves.

And that’s only natural:Most of us have been taught from a young age that mistakes are bad,and we should try to avoid mistakes.We’ve been scolded when we make mistakes—at home,school and work.Maybe not always,but probably enough times to make feeling bad about mistakes an unconscious reaction.

Yet without mistakes,we could not learn or grow.If you think about it that way,mistakes should be cherished and celebrated for being one of the most amazing things in the  world:They  make  learning  possible;they make growth  and improvement possible.

By trial and error—trying things,making mistakes,and learning from those mistakes—we have figured out how to make electric lights,to paint the ceiling of the Sistine Chapel,and to fly.

Mistakes make walking possible for the smallest toddler,make speech possible,and make works of genius possible.

Think about how we learn:We don’t just consume information about something and instantly know it or know how to do it.You don’t just read about painting,or writing,or computer programming,or baking,or playing the piano,and know how to do them fight away.Instead,you get information about something,from reading or from another person or from observing usually...then you construct a model in your mind...then you test it out by trying it in the real world...then you make mistakes...then you revise the model based on the results of your real world experimentation...and repeat,making mistakes,learning from those mistakes,until you’ve pretty much learned how to do something.

That’s how we learn as babies and toddlers,and how we learn as adults.Mistakes are how we learn to do something new—because if you succeed in something,it’s probably something you already knew how to do.You haven’t really grown much from that success—at most it’s the last step on your journey,not the whole journey.Most of the journey is made up of mistakes,if it’s a good journey.

So if you value learning,if you value growing and improving,then you should value mistakes.They are amazing things that make a world of brilliance possible.
