But I see that exercises that are just traps can be demotivating.

I'm not sure how to write more motivating exercises, however, how would
they look like?  Maybe like, you think it returns 3 but instead it
returns...the perfect Christmas present you were looking for?

#+begin_src emacs-lisp
  (if (you-think-this-is-non-nil-but-isnt)
      3
    "You should buy XYZ.")
#+end_src

Have to think about it...
