This one can be quite revolutionary, actually. I'll give you an example from my own life. I've always wanted to have a book published. Always. I've also been told countless times that it's really, really, really difficult to have a book published.
First, of course, you have to be willing and ready to write a book. And, if you were wondering, that is a lot of work. Then, you have to attract an agent. And, agents get thousands of submissions a year so it's a big challenge to stand out--especially as an unknown first-time author. Then, the agent sets out to find you a publisher and guess what publishers get? Thousands upon thousands of pitches from both agents and writers. They choose the pitches that interest them the most and ask for the full proposal which, by the way, is about 40 pages long and acts as a sales document for the book. If you are lucky enough to get a deal with a publisher, you then have to deliver the manuscript knowing that the publisher now owns your idea and could decide to cancel at any moment. Yep, they can pretty much dash your dreams if they end up deciding it's not worth the financial risk.
So, why would anyone even try to navigate this risky and perilous journey? Why would anyone set out to conquer any risky and perilous journey? Because the final result is worth it. Because when you reach the end, it feels mighty fine.
And, how do you continue to move forward? Luckily, that part is pretty easy. You simply make your choices based not on the fear that could easily stop you at any given moment but on your hopes.
