25 Fails for Life Coach Training

So I signed up for Life Coach training that starts up in March, a whole quarter away. My Impossible goal is to have the Life coaching (eventual) revenue to replace my current income. My question is, while I am waiting for the Training to begin, how do I plan 25 fails for that goal when I haven’t yet started? Should I plan things around the self-coaching work that we are doing in scholars? And what would that look like? I feel like I am stuck in not knowing what I do not know yet.
I am so excited for this opportunity to grow as a person, have the tools to manage the squirrels in my brain and be able to start empowering people.
