If you created a category in your mind that is "Google-worthy"* developer, that prioritizes above all specifically the niche of Software Development that your struggling with, I believe it is a sign that you should not keep trying to pursue this specific goal.
But I do believe you should try to be a software developer at all before you decide what exactly what kind of software developer you should be for all your career. You have never worked with software developer and you are willing to consider only one aspect of it "worthy"?
*A comment, google-type whiteboard interviews does not mean that they do select better software developers. It is a bias, not necessarily a bias to the best ones.
