Hi Piperboy,
Good question - lots of good sensible answers .... BUT once you decide on what's good **it and what's just **it ....... the big thing is the discipline to action it properly every time.
As you probably know the airlines run standard operating procedures (SOPs) to avoid the screw ups that winging it inevitably brings .... in most airlines if you don't RIGIDLY stick to the SOPs you're in trouble.
It's the deviation from good habits (airmanship) that normally gets you - notwithstanding the need to deviate when you need to deviate.
Best
