Increasing Belief When You’re Used to Poverty

I am truly working on increasing my belief in myself to create my business. My dream is to become a full-time coach and leave my county job.
I used to feel trapped by this job even though I did enjoy a lot of my work. I just know I don’t want to work until I am 65 plus. I want to be able to work for myself and ever since I could remember I wanted to create a business with attempts here and there with no long term or wild success.

I really want to become a fully book coach and leave my job within 2 years, but I also feel like this won’t happen soon enough. This leads to fears and reminders of coming from background of poverty and where my parents are immigrants. I just feel like we are always meant to struggle and overwork ourselves, but I do not want this anymore! I want abundance and confidence and possibility.

How can I increase my belief? I truly try to do models on this and try to work through the fear, but is there anything else that could help?
