Immediate panic sweat.
That being said, one of the reasons I looked to join Aideron Robotics (an awesome decision BTW) was because I felt it was time to overcome my reluctance to make a fleet instead of simply joining them and a larger corp would be more conducive to that goal, and I had plans to start doing so after I had settled in and got to know everyone. Like in a month or two... or a year.
But there I was with 6-7 other pilots and fleet boss, so I decided to grab the reigns and make myself lead. The panic subsided as I knew what to do. No hostiles nearby active, so find plexes and run them. The nerves subsided and the lessons I internalized from every fleet in 6 years I attended came to the fore.
To be fair, it was a very quiet night with the Caldari staying away. The closest thing to excitement was when a friendly got in a fight with some neutrals in Nennamaila and asked for help. I led the fleet in a headlong rush to get in there and tip the scales in our favour. We got Enaluri up over 50% like the previous FC wanted and we called it a night.
It felt good, surprisingly so. I plan to continue my efforts to develop this underutilized part of my game. There is no way this could fail!
