Warriors: To be a good warrior is to operate every weapon you know in the same way. Probably you will not use the knife against somebody with a some shooting-type weapon... even if knife is what you like the best :-)

Programmers: Never stick to your guns! First is the problem, then it's the technology and knowledge to solve it. Even if you have a supreme technology but don't have enough knowledge, you won't win this fight (as you should).

I prefer Perl over all, but i know, that sometimes i'll have to use something else - to chenge my handy-heavy-artillery to something like a long wooden rod, where what we mean as 'sharp' is only abstraction :-)
I suppose that everybody here have their own candidate to this role :-)
