There is a miss conception that you are born with some abilities and you cannot change this. So if you are not good in something you cannot develop them, like if you don’t have a good memory you cannot change this situation, you are stuck with the current you and you cannot change it!. This is not true, all abilities are malleable, you can change them with practice and right learning. If some abilities are important to you, start practicing them, give them enough time that your mind start responding to them.
There have been numerous studies conducted around the world which proves this theory that abilities can be changed, and people who believe that they can acquire whats required to be successful, really achieve success and those who think they stuck with abilities they have and they cannot improve them are failures.
