I think that the languages and platforms used shape the way one thinks about programming more than anything and that being exposed to different ecosystems is important. For example, working in a team of experienced developers that uses Java will probably rid one of most "cowboy coder" tendencies and instill a tendency for reflection on architectural patterns, etc, however it can also lead to over-engineering, "architectural astronauts", etc so then going to a more dynamic platform like Ruby on Rails (or at least using their methodologies in projects) helps balance this out. Programming is constantly evolving and it can be hard to figure out which patterns and processes to follow but one thing I feel is important is working in teams as it provides a good way to gauge yourself against others and help expose your own weaknesses.
