One observation of mine, after reading the first two chapters of a book which provides an overview of neuroscience, is that change is constant. Of the nine models of the nervous system described early on in the book, it is quite likely that the physical structures within your brain are constantly in flux.
For you that is good news. When you know your brain is an adaptable, ever learning, ever growing part of your body, you know that what you are capable of today is in no way a measure of what you were capable of in the past, and more importantly, what you will be capable of in the future.
I will be digging a bit deeper every day, so there is more to come. Yet when somebody tells you you cannot, you are not smart or able enough, now you know all you have to say to them is: “..yet.”
