easy.  Because it's a lot more efficient than traditional study
methods, you can either greatly decrease your time spent studying, or
greatly increase the amount you learn.

Anyone who needs to remember things in their daily life can benefit
from Anki.  Since it is content-agnostic and supports images, audio,
videos and scientific markup (via LaTeX), the possibilities are
endless.  For example:
@itemize
@item Learning a language
@item Studying for medical and law exams
@item Memorizing people's names and faces
@item Brushing up on geography
@item Mastering long poems
@item Even practicing guitar chords!
