I was a nervous flyer until I piloted a 737 completely from power off to takeoff. I did the exact moves that I HATED as a passenger. Turns out you can’t control the wind and ATC transmissions eat into your mental capacity sometimes leaving you “behind the ball”. The result was a take off flying above speed causing the auto throttle to reduce engine speed greatly (the feeling as though the pilot turned off the engine in mid climb), turning to match ATC requested heading and banking a little bit more than expected passenger comfort, and finally reducing flaps without banking or otherwise reducing AoA giving that weightlessness rollercoaster feeling during the climb. All of this in a span of 5 minutes.

Once I got into our regular flight profile and following our flight plan, I just sat back in my seat and let out a hysterical laughter. I am the calmest person when I fly now :)
