honestly i think of the time i would have uploaded my first page of my comic in march and then got cold feet and posted it april 1st without thinking XD now all my aniversaries have to be joke worthy.
I understand tho! When i was very young often got a sickly feeling about uploading, expecially when i felt like no one was reading >> but its important to remember that even if you have one reader or one revewier its still at least ONE person excited to see what you got.
and sometimes if you got the nervous issues the best thing to do is tell your self "too bad doing it anyways- now or never!" give yourself and ultimatum. even if its as small as "ill let myself have some oreos as reward for finally uploading" or some such XD
at least thats how i deal with all the D&D games i DM ^^'
