In my personal case I am not sure if it didnt end up 'bad' for me. The first language I've learned was 6502 ASM on C64 (and learned is a word of many degrees here, I can't say I've written anything serious in it, ever) and for some reason I've been struggling with many other languages for years to come after that - tried Perl, PHP, C, AmigaE, without being able to grasp any of those. Until I've met Python, that in few days took me from ground to the stratosphere (which today again looks like a ground, but that's a different subject). And even then, old habits of counting cycles and thinking about what the hell is the language doing made me to prematurely optimize my code (like doing 'while 1' instead of 'while True' because in 2.7 True is simply a variable, what means the interpreter will have to check its value first and that means lost CPU cycles, and lots of other things that made sense in 6502 ASM) instead of getting it to do shit ;) It took me a while to 'unlearn' those habits and to simply enjoy the language in its own form.
