The only time you have too much fuel is when you're on fire. Low on fuel and on fire. A single engine jet is a triple emergency. The only thing worse than a captain who never flew copilot is a copilot who was once a captain. A terminal forecast is a horoscope with numbers.
Takeoffs are optional.
Landings are mandatory. The first thing every pilot does after making a gear up landing is to put the gear handle down. A great landing is one which lets you use the airplane another time. A good simulator check ride is like successful surgery on a cadaver. Good judgment comes from experience.
