I echo what has been said.
Remember in flying you never know it all. The day you do is the day you are complacent. Just keep at it and you will improve. Also, remember what you find personally beautiful about flying; it is that that keeps you going. Tonight I was flying passengers from Africa to Europe, I turned down the cockipit lighting and for a while I had that bit of magic with the stars very clear and the land lit up in the moonlight.
p.s. I am still struggling to learn as a new FO.
Best of luck,
Tom.
