" As a beginner, your mind is empty and open. You’re willing to learn and you are receptive to all new information. As you develop more knowledge, your mind often becomes more closed. You tend to think, “I already know how to do this” and you become less open to new information.
The problem is that when you already know a lot, you actually need to pay more attention, not less. Why? Because when you are already familiar with 98 percent of the information on a topic, you need to listen very carefully to pick up on the remaining 2 percent.
And why does that 2% matter? That 2 percent is what the greatest athletes never miss and that's why you see them never plateau."
As we get better at something we also build up the understanding of it. Whether the subject was the World War 2 or Running, we can only build up our understanding of the subject on top of what we already know about it.
First we learn the "bigger picture"; who was fighting agains whom or what movement creates running. That's how much we can learn and understand when we begin. But is that it? The World War 2 can be understood by simply who was fighting against whom? Or that running has no other nuances than a step followed by another step?
No that's when we have learned the basics of it and that's when we can start understanding the relation of the smaller things with the bigger picture as it now has a meaning to us.
We learn things in terms of meaning. Finding meaning in our learning is the key
You can always learn new if you keep your mind open to it.
First you have an open canvas, then you paint the rough lines on it and then you add the small little details.
So it goes with learning any movement; first you learn the basics, then you learn the little details as they now makes sense to you as you understand the basics. You can connect those details with your experiences and make them mean something in your practice.
Often times this means that we learn something, then we challenge our selves; whether it's with weights at the gym or by distance in running. At this stage we maybe hit a small bump on the road as we understand that we are no longer progressing. So we go and study the subject a little more, we learn something new and understand that we are not able to implement that new information without taking a little step backwards (unloading the barbell or lesseninng the distance or speed). We practice, so that we can implement that new information. As we then learn to do that, we progress again with the weights or with the distance. Having improved our technique by learning something new we now stand a better chance of progressing further than where we were before.
"Why haven't I learnt this before?"
"Why haven't I learnt this before?" or " Why no one ever told me about this before?"
Probably you have came across that same information before, but you don't remember as you couldn't find a meaning for that information before as you weren't where you are now, knowing what you know now.
Probably your coach also left that information out as they knew you couldn't have been able to absorb that information before as you lacked the basic understanding to build up on.
What ever case, you can only learn so much on one go. So don't feel bad about yourself for not knowing it all yet, because you never will. What actually matters is that you never stop!
As long as you are learning, you are progressing.
