You are your own worst critic-if not: you should be! Always strive for accuracy-don't accept 'near enough'. If you are on a long, marginal fuel flight never pass a fuel stop along the way. Keep a close eye on Temp/Dewpoint splits (even if the forecast is benign) especially after 0400! KNOW your aircraft limitations. Always leave the aircraft how you would like to find it! Enjoy the view: this helps your lookout. It is only a dumb question if you DON'T ask it. Remember, you are worth what you think you are. HAVE FUN!
