Having an open mind to unfamiliar programming languages and technologies is a good thing. An open mind is especially useful in a field that changes as quickly and drastically as software. This seems so obvious to state that it’s almost cliché. Adapting to new tools means more than bringing your old habits with you. If all you've ever worked with is a hammer and somebody hands you a screw driver, reserve judgment and do a little research on screws before complaining about how your new tool doesn't pound in nails very well.
