You're going to fuck it up sooner or later. Even after you make it, and get someplace with your ambitions, sooner or later you will make the mistake that gets you back into trouble. Even if your discipline is spotless, and your analysis is flawless, there's always that Black Swan event that comes out of nowhere and blows your situation into pieces. Failure is inevitable, but it need not be final.
Remember that patch release for World of Warcraft from yestereday? Already they're taking a list of things that they fucked up and are fixing them as fast as they can, in order of content priority (so the raids get fixed first, etc.). Sure, there's some fuckups that I'm pissed about (Scaling NPCs to your character's gear level is the dumbest thing they could do; it actively punishes you for playing the fundamental point of endgame content- gaining power by gearing up.) but that feedback they're getting (and getting good and hard) will push them to fix their failures right quick.
For all the shit the dev team for WOW gets, they are getting better at fixing their fuckups. Already hotfixes went out on the top priority fuckups, and more are on their way in the days to come. (But that gear scaling thing? It needs to die, screaming, like it got used as a target dummy by Daleks. That's a fucking retarded idea.) There's enough people on and near the team to get action going right away, and that's a good thing.
They knew they screwed up, caught it early, and immediately began fixing their errors. That's (a) knowing that they're going to screw up somehow, (b) having methodologies in place for error occurances that they're experienced with (but haven't actually solved yet), and (c) know as an institution that Fail Faster is the smart way to go. You should observe this and learn from it. No matter what you do, seeing this skillset and talent stack in action is a good demonstration on why having a talent stack (in this case, in the team as a whole) and a system in place to use it (known procedures for these occasions) can only help you recover when you do stumble but also lead to wiser courses of action going forward.
