i thought before that i can fly to every airport, i have the skill and i dont need to be afraid of that.
To an extent that is true...
I've been flying to CV41 for the past 3 months, so it doesn't matter if I fly to CV63 or CVN69 -- they all look the same from the cockpit...
OTOH, there is no terrain around any of them, and I don't have to worry about runway length.
OTOOH, if I have to divert to an airport that doesn't move, I might forget to turn on the antiskid, and run off the end of the runway...
Stuff like that happens. Study the charts for the airport for EVERY landing!
