show me how it works

I need this to be explained to me:

Oh you failed math, ok we will give you another chance.
And then you fail again, and again and again.
More chances and more chances to do the same thing.
But its ok to not study more or go back and see what you did wrong.
Because what is the point when you know there will be another free chance.
This can keep going on forever until you just get tired and never feel the need to pass anyways.
Why even strive to learn? What is the incentive. What is the motivation?

But I wonder if you knew you would not be given another chance.
That the consequence was failure and not passing. And that you need to pass to improve yourself.
To get to the next level of learning and to understand the world around you more and to get a job and to earn money and to .... everything else down the chain.
Would that be motivation? Incentive? The idea that failing is a bad thing and that succeeding is a good thing.

But if you are given chances and not taught what was the mistake or what was wrong. Not able to learn from failure. Not even to be told that failure was a bad thing, that it had consequences. That all our actions had consequences. Even told that failure was ok, it was ok to not learn to not strive to improve yourself, that there was no goal, just to be.

I am not sure what the whole point of it is all.

Someone please explain this system of complacency.
