  - We empirically investigate the impact of successful goal achievement on future
    effort to attain the next goal in a recurring goal framework. We use data from
    a popular German Question & Answer community where goals are represented in the
    form of badges. In particular, our analysis of this data hinges on the fact, that
    in this Question & Answer community, badges in a hierarchical badge system are
    in-creasingly challenging to attain up to a certain badge. After this certain
    badge, the difficulty level sud-denly drops and remains constant throughout up
    to the last badge in the hierarchy. Our findings indi-cate that after successful
    badge achievement users increase their subsequent effort to attain the next badge,
    but only as long as badges represent a challenge to the user. According to our
    analysis, we identify self-learning to be the key driver of this behavior.@eng
