Scientists have shown that the brain does not fully harden in a person until the age of 25, which is remarkable based on the fact that our brain needs lots of years to fully develop and makes many changes as we are getting old, and then once we actually hit the age of 25, our brains harden and stay like that for the rest of our lives.
So, when mastering a task, we have to change and start up places in our brain. When we first start this goal we want to achieve, such as a sport or talking in front of others, our brain knows what we want to say or how we want to carry out the performance, but when it is time to actually do it, it goes the opposite way of how we wanted it to go, and soon our brain gets more comfortable with the action as we do it more. So, during these twenty-five years before the brain is fully hardened or close to fully hardened, many changes happen through our brain. As the ted talk mentioned, overdoing a performance can worsen the performance itself, but underdoing will get you nowhere, this is why moderation should be a key to making and helping your brain achieve the goal.
Practicing moderation is so good for health to your brain, staying healthy physically, and even achieving your goals. For example, you want to run a distance in a specific amount of time, and you barely eat because you are just so focused on doing it right. This is not only unhealthy, but a bad way to achieve and accomplish something. With moderation, you could practice a little every day or every other day, or even a couple of days week at minimum and have the nutrients you need to practice for running. However you do still need to practice a good amount in order for your brain structure to change and for you to be more comfortable doing it and with moderation, it gives you a steady pace to slowly but successfully achieve your goal rather than doing the all or nothing way, which sometimes ends up working but could also drastically fail.
