i get that feeling too, but until 5 or 6 years ago i only used it for org-mode & 1 or 2 minor prog modes.
there is so much to #emacs that it's easy to feel inadequate but identifying what package would improve your work flow isn't the easiest thing to do.
it's only in the last year that i've started to use use-package & that was due to one of Prot's videos actually showing me what it actually does.
