After plenty of disappointment (ok I must be just here, I have SO MUCH to be thankful about), I am now faster at seeing when something is not feasible. I don't even have to be told something is not working. Before this I would somehow manage to believe otherwise until I actually hear it from various credible sources. I would believe that things always had the potential to turn out for the better. I believed things happened for a reason.
This must be learning by doing, this is maturity, realism, rationalism. Now I know what I expect, and I know I won't be able to expect less (why should I?), I know what's realistically possible and what's not, so there's no point in naivete and stupidity. And I don't even need to be told that. Silence is enough. How convenient is that?
