It's actually okay: you come up with abstractions as a result of
abstracting things out, :) not the other way round.
I'd advise you to read "How To Design Programs". Unrelated to Haskell,
it shows a bunch of nice examples of abstraction, including the steps
required to get there, with motivation and justifications. The books
is aimed at beginners in programming, but don't let that discourage
you: it has good ideas to share.
