I am scared of chain reactions

I am getting a new graphic design job in a agency as a newbie. when I think about how this all started I get the flashback of some website which I think I firstly saw about the software I am working on, I gone to that website now, I am so worried to find that it was a copy paste trash website with a very poorly made art on the cover, I can make things better than that now, I browsed it so much when I was a kid, like I loved reading things about software, computers, and stuff, I am very scared it is all because of a copy paste trash website running by someone who doesn't know anything he was talking about, like everything in my depends on the job now, and I got interested in art because of I started creating things digitally.
