I think the Zen Buddhists have it. Most of the thoughts we have are centred around avoiding having to deal with what is right in front of us. In otherwords we are constantly shirking things. The good news is that everythig one is inclined to shirk is an opportunity to develop character by simply doing it and sticking at it until it is done. The Zen Buddhists also repeatedly refer to judging things as good or bad or "picking and choosing this vs that" as the primary shirk mechanism. In my case this is definitely true. Lets face it. Conceptually CS or programming is a very limited domain (compared to something like, say physics, or even electrical engineering). I used to program in C++ all the time. What have I picked up since then in working with/reading about other languanges? I mean what have I picked up that fundamentally/conceptually new? Nothing. (The functional stuff certainly does not introduce any new concept. Objects/interfaces are first class collections of functions)
So bottom line is that if I am honest, experimenting with/reading about other languages has been a net loss for me. The only reason I do it is literally because its a form of shopping as in "Modelling real world problems is hard, let's go shopping"
