Imagine you're in a car accident and your car is damaged.

Generally, when the amount of damage exceeds the worth of the vehicle, it is more cost-effective to simply purchase another car.

I suppose I am trying to apply a similar logic to my life, although I realize that there are a lot of inconsistencies with this analogy of a car compared to a human being. In any case, I just want to know at what point, what point can I say that I am a "totaled" human being not worth repairing? When is damage too much damage? I suppose I am a little wary of being gullible and naive in thinking that there is no such thing as 'too much damage,' and I don't really want to waste more time than I have too trying to fix something beyond or not worth fixing.

I suppose a similar, and perhaps less loaded question would be something like: At what point does someone cross accepting their limits to giving up on their dreams? What is the difference between these two things?

I am not fully convinced of the notion that humans cannot fail, only actions. Don't our actions reflect a quality in ourselves, especially actions that are often repeated?
