Wanted to take a chance to share one of my favorite pieces of content that back up what ReyCuervo is saying:
I can relate to this line of thinking from early in my career. I wanted to be a fiction writer and didn’t want to be anything else. Unfortunately, that’s not how life works and I got knocked on my ass a few times (especially when I realized I wasn’t as good as I thought I was). After you can’t pay your bills and are almost homeless a few times, you realize you need to re-evaluate what you have to do to be successful.
On that note, there are plenty of famous artists, writers, film directors, etc. that had to take normal jobs to pay their bills while they worked on their dreams. I used to refer to my technical job as my “backup plan until writing works out” so at least I had two paths going and something to always fall back on so I never wound up in a bad situation. Either way, at the end of the day I wasn’t relying on my talent (or lack thereof) as a writer to pay my bills.
I only offer this information as an example of what you can do until you make it (if you make it). It’s a cutthroat world out there, and sometimes you have to have multiple plans going to survive.
EDIT: Combine this with the law of attraction as Eva mentioned, and you’re likely to be successful.
