Hi all,
Wonder if anyone could tell me what I probably already know

I am in a position where I am aiming for my goal to be a full-time Hypnotherapist and also to concentrate on a part-time side line in audio equipment supply aimed mainly at the therapy market.
I am currently working full-time selling audio equipment for a company and have been doing so for over 10 years. I have a good amount of knowledge in this field.
I am finding it harder and harder to concentrate on my "proper" job as I have so much I want to do with my own projects- I love doing my thing and want to do it more and more.
I had planned to phase my stuff in over time (weekends for the Hypnotherapy and spare time during the day on the audio business) but I'm not sure it is working. I feel the need to do this for security, but another part is telling me to just jump and go for it.
My main fear is (as far as I can see) that I rely on my regular wage due to repayments on loans, credit cards etc as well as normal monthly bills. It is almost as if I know I would succeed if only I could freeze all living expenses for 3 months while I got down to it!
So I guess what I am asking is if anyone else has been though this kind of dilema and if so, what happened?
Been meaning to post this for a while but just got the courage to!!!
