Tony Hsieh from Zappos famously does one thing a day that scares him. At a certain point, potential failure is as scary as just trying something new.
If you're weighing an option that opens you up to a higher risk of failure than other options, then depending on what type of person you are, you may have to evaluate whether you have enough of a support network or other "cushion" to absorb the mental blow of failure first. Failure is something that can be gotten used to, but before it is, you have no choice but to get past the damage to your mental health the failure causes, and some people are not capable of managing that on their own.
This is why I have to sometimes frame my decisions as: "Because I will fail considerably more often if I choose this path, I'm giving myself a considerable risk of becoming a miserable wreck incapable of doing the things I'm capable of now, or worse. So for the sake of preserving my mental stability, I will have to do something else."
