Not really. I learned to code Pascal 16 years ago, because I wanted to make DOS computer games.

And here I am now: 10+ years of professional web-dev experience, spoke at local dev conferences, won awards for my work, etc..

What I learned during all these years is that methodologies and models help you after you learn how to build apps/plugins/games/whatever. And still they won't save you from wasted hours hunting an accidental typo.
