What exactly is memoirs? Anyone with any amount of life experiences can write memoir - it might be a life changing events or a reflection of period of growth.
We, people actually started from scratch. Unknown, just a nobody -- but our time probably will shine "just believe in yourself" then someday, you'll probably reminisce the past,,,
Where you aren't the best version of yourself yet, just a nobody standing in front of people who laugh at you and not believe to your capacity.
-- These kind of people motivated you, you want to prove that they are wrong. That you aren't the person who they think you are. Then one day, they will tap you... "sorry, we're wrong! We should believe that you can..."
All the disappointments, failures, people who belittle you and such.. are just memoirs and life experiences for us to grow more and to be strong inspite of challenges in our lives..
A memoirs that someday we'll look back and laugh and say... "I did it"
