That's certainly a problem, too. I'm suggesting that it's useful to really kindle an interest before starting in on the harder parts of studying it, not that the harder parts should be put off indefinitely. In particular, learning the hard parts early may make a person dislike them more than they should, e.g. biologist's might see p-values as some annoying hurdle to clear rather than a useful tool for finding real conclusions.
