“You know, my motto is ‘Excelsior.’ That’s an old word that means ‘upward and onward to greater glory.’ Keep moving forward, and if it’s time to go, it’s time. Nothing lasts forever.” – #StanLee

My Tribute To Stan Lee… The reason I drew Spider-Man is because that was my childhood and teacher of how I see life. Spider-Man taught me Family, Love, Loss, Never give up and Do what is right, ALWAYS! Even if it hurts you in the process, but you know it’s the right thing to do pic.twitter.com/RSOejJHjTe

Lee, who was born in 1922, began writing early in life. In 2008, Lee was awarded the National Medal of Arts, the highest government award for creative artists.

Speaking to the media after his death, Stan Lee’s daughter JC Lee said her father loved what he did for a living, and was loved by his fans and friends. Stan Lee would remain irreplaceable, she added.
