If you want to get good at something, you're going to have to work at it. No one else can give you a shortcut to common sense that comes with mastery. Only pointers. That's just the way life works.
I can figure out how to look up these projects myself. The point is, if you are going to give examples on error handling be more specific. I don't need any general "life lessons" here, the point is it looked like you were trying to make a point, without having one. I.e you did not actually have any examples, you only made it appear so.
