Reinventing the wheel
There is nothing wrong with reinventing the wheel. Wrong is not abandoning your wheel when you find another one that is significantly better than your own.
Anyway, as I have found the hard -- and therefore, more convincing -- way, "to reinvent or not to reinvent" is hardly an essential question. *The* essential question is, what will cost me less, reinventing or adapting? From that perspective, the glory of achievement seems to diminish rather fast.
