Something.

Read something interesting recently.
Example:
In high school, a young girl can put in hours of work to perfect the craft of cheer leading. This activity of seemingly low importance, is perhaps number one on this girl's daily list of things to do, possibly above the importance of her studies.
Years later, coming from the perspective of a grown woman, witnessing current adolescsents cheer leading in passing can provoke feelings of disgust and annoyance in regard to how useless the activity would be in adulthood. What she failed to realize is the hidden important in such activities as an adolescent; how they can potentially teach us the significance of dedication, of perseverance and most importantly, of meeting small goals to ultimately meet a bigger goal. Although cheer leading was just a phase for her, it probably led her to be a more well-rounded woman with all the useful morals instilled within her all because she was willing to dedicate hours daily to a seemingly menial activity as a teen.
It may seem as if this theory is far-fetched...but do not forget, the mind if powerful thing, it can make connections that we will never be aware of but still utilize.

I also briefly touched upon an aspect of the goal-meeting theory of humans.
We as people, cannot live without knowing something is worth it. Nonetheless, I'm fully aware that people perform certain activities out of pure enjoyment of the activity, not the goal. Let's step outside the and see this as a completely uninvolved and un-opinionated person...isn't the enjoyment DURING an activity the same as AFTER? Well, the answer is yes and no. Yes, because we were made to be selfish beings, we as intellectual and thinking being were created to benefit from our activities whether it be before or after. Also, to cover another base in this argument, even if we're performing an activity purely to benefit another, we'll still generate some sort of subconscious pleasure derived from knowing we did something for someone else. We may or may not be aware of this, and if we are, we may not always admit it just to seem pure at heart...although "pure at heart" is a relative term; it was created by Marxist and Communist-orientated people to sway the public into thinking that everything should be done selflessly. This, in essence, creates a negative connotation for individuality and the innate human-nature of obtaining something purely for ones' benefit.
As for the no, the only clear difference I see is WHEN the self-benefit actually Curr's.
