I started making a comic when I was in grade 10 (1987) based on a character I created. I got a splash page and the first page penciled with lettering, felt really proud of it and showed it to my art teacher (also a comic book fan). He picked apart those 2 pages so harshly and the final nail in the coffin was his "work like that won't get you into Marvel" comment. Even though I am a freelance illustrator with a respectable amount of work to my credit I was crushed by what that teacher said and did not even try to draw sequential art in any form until this year (2016).
When I became truly confident in my ability and didn't care what anyone thinks of the story or characters etc, I wanted to see what it was like to finally make a comic (of any page count) I can tell you I felt a mountain lift off my shoulders when I completed and posted it here and on Comicfury. Completing that first comic allowed me to move past a "block" that I didn't even know was there and the new "freedom" has greatly improved my other artwork and attitude towards it. The comic even has 18 subscribers which is nothing but is 18 more than I ever thought I would have. And that feels good too. Finally one of my regular customers an indie film maker, saw the comic and offered to direct an animated version should I ever decide to go that route.
So, pick up those goddamn pencils, drawing tablets, Papermate pens and open up Word or pull out the type writer and create you glorious creative bastards and CREATE, POST, PROMOTE then repeat. I am not a fan of every webcomic I see but I AM a fan of the creative process and the comic book medium and hope it always stays alive.
Thats my 2 cents.
