NOT TRUE! And please don't let anyone convince you for any reason that you can't learn something. Even if your motivation is just to pass a certain math or english test in order to get a job, you CAN learn. Brain research tells us that our brains are still growing well into adulthood and that they are very flexible. That means you can train your brain, just like you can train a muscle to perform.
Many adults get frustrated trying to learn something new. That's because you are have become used to problem solving in your grown up years, taking care of family, house, job responsibilities, etc. You are used to making quick decisions and getting results fairly quickly. You have become specialized in the work you do for your job and your family and are just not used to thinking about academic subjects. To a certain extent you have been running on autopilot.
And now it's time for you to take over the controls again.
Let's say you have a room in your house that you used for storage. It is filled with the odds and ends of your life. Now, you want to use that room for something new, let's say a hobby or a guest room. You will have to remove and reorganize the items you have stored in that room, maybe choose a new paint color and some furniture and curtains and re do the room so that it has a brand new function.
You can do the same thing with your mind when learning something new.
As a tutor I help you to move and re-organize the information in your brain that you don't need for this new task and set it aside. Then we dust off the items that you want to save and use, and then choose the new information in such a way that it fits together nicely with the old information to form a brand new room in your brain. One that functions in the new category of learning.
It's simple. It just requires an attitude of "I CAN" rather than the excuse of "I'm too old for this." :) Happy Learning!
