I agree with others that this is a very bad idea, and would encourage
you to change your habits.  However, for the sake of showing how easy it
is to modify 'define' to act the way you prefer in your own modules:

(define-syntax define
  (with-syntax ((guile-define #'(@ (guile) define)))
    (lambda (form)
      (syntax-case form ()
        ((define (name . args) str)
         (string? (syntax->datum #'str))
         #'(guile-define (name . args) str str))
        ((define . rest)
         #'(guile-define . rest))))))
