Is it a good thing?

Perhaps the monumental degree to which I fucked up as an adolescent and a young man granted me a sort of early wisdom that helped me avoid making the same sorts of mistakes at a later age... This would be fortunate in the sense that at those later ages, the repercussions are much more severe and "tangibly long-lasting".

Of course most people would look at a term like "pre-emptive disillusionment" and instantly view it as a negative, but I think that value determination is entirely debatable.
