Maybe results are a lower bound of your ability; whatever you achieve means that you are at least on that level and achieving low doesn't rule you our for achieving what someone else has that has achieved more.
Probably a very optimistic perpective but meh.
Also remember that even though if feels important, there's a lot beyond vce. To put things into perspective:
Math/Science example:
*Grade 3: spitting out times tables as fast as you can determined your place on the retard to genius scale.
*Year 7: Similair to grade 3 only more variety with questions
*vce: Manipulating boring algebraic expressions, plugging in numbers as quickly and mistake-free as possible and deciphering almost ambigous statements. Memorizing disconnected facts in a random order.
*undergrad: Similair to vce but more sophisticated, the actual lecturers are more respectful/entertaining. Facts not so disconnected.
*postgrad: Proving some theorems.
*PhD: analysing the inner workings of some specific result.
*Nobel Prize/Fields Medal: Extending some area in a possibly elegant and insightful way.
*Senior: Inspiring the next generation, finding the next Ramanujan.
Arts:
*Grade 3: spelling words with silent letters well.
*High school: writing fluent essays and memorizing possibly meaningless books.
*Uni: learning some interesting shiz.
*Later: Contributing something intelligent to society. (sorry, i don't know much about arts)
Simply, things get more significant and you place less emphasis on the past; realising that, for example, vce is a very incomplete picture of reality (compare year12 math to grade 3 timestables as an analogy for those who do not know this yet).
