Try to think back as far as you can and find the earliest memory you have. My earliest memory is when I was 3 years old and woke up literally clueless about everything. I didn't know where I was or what my name was and had no memory if going to sleep the previous night. Eventually I learned my name and the relationships I had with people like family and friends. Believe it or not, but I promised myself, at 3 years old, to never forget that moment and I'm surprised I've actually kept to my word on that.
