Entrepreneurship and fear!

Fear! Paralyzing! I have a side business that I have kept undisclosed at my full time job. It is in no way in direct competition nor I am approaching my company’s clients. That said it is a very small office and as it turns out I’ve been running in the same circles as some of my day job’s clients. I even networked with a client’s daughter (did not know that at the moment). My question is I am extremely fearful of my employer finding out or any other scenario (running into people that know me, etc). I am not resisting the fear neither I’m letting the fear stop me. I’ve been writing my blog post, doing my work and networking all while scared out of my mind. If I am feeling the fear (terror really), how can I manage my mind to continue moving forward and start thinking thoughts that are more productive.

Thank you!
