I have a semi-successful side hustle that I've been running for 5 years now. It's been really fun but my business is mainly entirely online. I also mainly do social media marketing for it and email marketing. I've kind of hit a peak though with everything I can do online and I know that there's other things I can do like setting up a booth at a relevant place for my booth, or pitching myself for investors, etc. etc. But I have extremely horrible social anxiety and nothing terrifies me more than talking about my business outloud to strangers.

Is there a way to be successful without doing those things that trigger me or is this all I can do?
