I have a different outlook as someone whose life was crippled by anxiety.
Many times my opinion on varying matters is asked I am met with some derogatory comments about how I only see the grim aspects of a given situation.
When in truth, from my point of view at least, I simply seem to see a large tree of possibilities of things that can go wrong or right. For instance, regarding the positive and negative sides of buying a house, if I point out the price, the distance to school/work and the condition of the roof it seems like people blame me for pointing it out... like I was personally and willingly trying to destroy the happiness the best case scenario would bring if they bought it on the spot. And it rarely fails: my objections are only met with more positive aspects in the form of "but this is okay because...". It's like most people don't want to see the whole picture, only the positive elements of the whole picture.
Now I try to grow up and dodge those situations or let requests for advices pass by.
But it's not about « intelligence », it's more about seeing the whole picture, getting asked about it and being blamed for detailing the obvious (I know next to nothing of carpentry or the real estate market beyond the obvious: "don't buy a house on fire").
