The biggest hurdle is to actually believe that you can get a job as a software developer.
Many people still believe in a "fixed mindset" and think that some people are "born to code", when the reality is that anyone can learn to code if they put in the time and effort.
There are so many open developer jobs. They are increasing in number all the time. And software development is already one of the most popular professions in the world. There are more than 19 million software developers out there, but that's nowhere near the number that the world needs.
Most people give up because they don't see the light at the end of the proverbial tunnel. But that light is there, off in the distance. You just have to keep going.
