The advantage of programming long enough is that your 'primary' language changes several times, and each time you get less zealoty about it.

Having learned a bunch of languages myself i would recommend beginners to learn a language thoroughly before moving on. Otherwise you don't assimilate the style of a language and end up writing fortran in c, or c in c++. The qualitative differences between languages don't become obvious until you understand why their common style is what it is.
