Succession is a hard road to walk for the successful. For the try-hards in life it's so much simpler: measure your failures, identify the necessary improvements, and apply a liberal amount of elbow grease to go that extra mile. But for life's winners, that road gets longer and steeper with every step.
For example: Bioware. Pity the poor company whose work is of such a consistently high quality that only they can manage to better it. The original Mass Effect, released in 2007, was not without its flaws, admittedly, but like all of Bioware's titles its few failings were almost completely obscured by the floods of awesome that poured from its every orifice. It was met with near-universal acclaim, and rightly so.
