Speaking as a professional with 15 years of career in software engineering under his belt: don't be so hard on yourself. I mean, I don't typically prototype or iterate on ideas in Typescript, either; I do that in Javascript, and reserve strong typing for when I know what I need to build, and it's just a matter of doing so in a way that's reliable, maintainable, and secure. The point is that flexibility and strictness both have value, and it's more worth knowing which is more useful at a given point in a project's lifespan than trying to be dogmatic about one or the other.
