I started in FORTRAN at MIT in 1960 and now prefer Haskell, OCaml, Ur/Web and SML97. Along the way, I picked up several (macro) assembly languages, wrote some DSLs, and dabbled in Objective-C before C++ became available. Since Haskell can now be as fast as or faster than C, I see no reason to go back.

My first program was at MIT in 1960. I didn't like FORTRAN (note: all caps required), so stayed out of computing until the late 60s. Then it was (macro) assembly language, Lisp (1980), C, Objective C (80's), C++, Scheme, Standard Meta Language 90, Miranda, Hugs, OCaml, Standard Meta Language 97, Haskell 98 and now working on Haskell 2010.
