Working backwards from Result

Hi! I want to leave my current job because I don’t want to find it to be rewarding or fulfilling and I’m not aligned with how I am required to spend my days. I do however need to replace the income to be able to support my family. I would also be giving up my pension and health benefits so I would need to make at least 200K to replace the income I’m currently getting. I went through a coach training program but I’ve only been able to get a handful of clients and made only 5K this past year. I’m starting to feel defeated and am wondering if growing my coaching business is something that I can actually do. T=I don’t have what it takes; I’m not good at this etc.
I would love some coaching on this.
