Scared of being judged and seen

I want to launch my business. But I am frozen in telling people what I am doing both in real life and on social media. I am trying to work out why I am so afraid of being seen. I feel like I am an imposter and then when I talk myself into actually doing something, then I worry about what people will say if I’m not successful.

I know there are multiple models here. And most of them result in no action or failing ahead of time. How can I change my thoughts so I can begin to move forward?

C – Business to launch
T – I’m worried about telling people what I am doing because they will judge me
F – Scared
A – Do nothing to stay safe
R – Nothing changes and I don’t move forward

Thank you.
