Believing in everybody else’s success but my own

Thank you so much for your help!!

I’m selling online courses and even before starting marketing them, people started buying my course, so that’s great!

I truly believe in the value of what I’m selling but here’s the deal: I think that I don’t 100% believe in my business and that I’ll be successful. When other people come up with ideas (for their businesses, etc.), I’m convinced that the only thing stopping them from being successful is their thoughts!  But, for me, I find that there’s something else and after tons of thoughts downloads, I cannot point my finger at what it is! My thoughts? 😉

Could you guide me? 🙂

Thank you so so much!!!
