Exactly.
"It's just the way things are."
"Be positive"
"you're not in the right mindset"
also i think the "find something you like to do and you'll never work a day in your life" mentality is kind of dangerous, i'm not saying it's not possible, but it could also result in making you hate what you enjoy.
i remember reading on reddit about someone who was a gamer, started to work in the industry and lost all of his passion towards videogames, no surprise: it's not only about what you like to do, there are deadlines, long work hours, underpayment, being forced to do stuff you don't like (both generally and artistically speaking), a lot of things to take into account.
when i was younger i liked to draw and wanted to make comics, then i read "bakuman" a manga about two young mangaka on their way to the top and, even if i'm not japanese and my pace of work would probably be less insane than their, even if the manga itself was super fictionalized, it was enough to make me say "what the fuck" and reconsider everything.
although, on second thoughts, maybe without all those doubts i would have made different choices, maybe i'd still like to draw today and maybe i would have something to keep me going, who knows.
