March homework

I have been consistently doing March’s HW and my thought to #1 is this: “I am completely capable of building my blog into a business and making $50k this year.”
My #2 response is “I feel like I can do it with consistent action”
but where I get hung up on is #3. I come back to “I don’t know the how”
When I look back at my answer, my 1st thought is “I don’t know” doesn’t serve me and also, Brooke talks about not worrying about the “how”. The “how” will change. So do I just commit to only believing that I am capable of building my blog and how I make the 50k will show up along the way?
