Hi everyone. One of the things that I enjoy is learning new things. How long does it take to acquire a new skill?
大家好。我有许多喜欢做的事，而学习新事物就是其中一件。习得一个新的才艺需要多久呢？You know what I found? 10,000 hours?! Nooooooo!
I am never going to be able to learn anything new ever again.
But that's not true.
The 10,000 hour rule came out of studies of expert level performance.
Professional athletes, world class musicians.
The folks at the tippy top of their fields put in around 10,000 hours of practice.
这些在各领域中的顶尖人物都投入了约1万个小时来演练学习，But that last statement- it takes 10,000 hours to learn something?
It's not true.
This is the learning curve, and the story of the learning curve is
when you start you're grossly incompetent and you know it.
With a little bit of practice,
you get really good really quick
and then at a certain point you reach a plateau
and the subsequent gains become much harder to get.
How long does it take from starting something and being grossly incompetent
and knowing it to being reasonably good?
Here's what my research says: 20 hours, that's it.
You can go from knowing nothing-if you put 20 hours of focused deliberate practice into that thing,you will be astounded at how good you are.
你可以完全不懂某件事——如果你投入20个小时刻意地完全专注于某件事的练习，你将惊讶于自己的提升水平。20 hours is do-able,it's about 45 minutes a day for about a month.
There's a method to doing this.做这个是有诀窍的，The first is to deconstruct the skill,decide exactly what you want to be able to do and break it down into smaller and smaller pieces.
第一是解构这个技能，确切地决定你想要做什么，并将它拆解成许多小单元The more you're able to decide what are the parts of this skill that will actually help me get to what I want,
你越能够决定技能的哪些部分是可以真正协助达成目标的，you'll be able to improve your performance in the least amount of time possible.
你将越有可能在最短的时间内来提升你的成果。The second is learn enough to self-correct.
第二是学到足以自我矫正。Get 3 to 5 resources about what it is you're trying to learn-
it could be books, could be courses, could be anything.
What you want to do is learn just enough that you can actually practice and self-correct.
你要做的就是学到让自己确实可以独自练习和自我修正。Noticing when you're making a mistake and then doing something a little different.
The third is to remove barriers to practice-
-distractions, television, internet.
And the fourth is to practice for at least 20 hours.
Now, most skills have what I call a frustration barrier.
注意，大部份的技能学习时都会出现我所谓的挫折障碍。By pre-committing to practicing whatever it is that you want to do for at least 20 hours,you will be able to overcome that initial frustration barrier and stick with the practice long enough to actually reap the rewards.
That's it, it's not rocket science.
The major barrier to learning something new is not intellectual.
The major barrier is emotional.
主要障碍是情绪化。Feeling stupid doesn't feel good and the beginning of learning anything new and the beginning of learning anything new... you feel really stupid.
But, put 20 hours into anything.
Do you want to learn a language?
Do you want to learn how to cook?
Do you want to learn how to draw?
Go out and do that thing.
It only takes 20 hours.
