Brain fade.. may you one day wear your four gold bars as golden feathers and not as lumps of lead.
Do not ponder too much from the sometimes lonely LHS that now you are the commander you are "Legally responsible for the safety of your flight to the extent of your worldwide wealth."
Stay single and invested all your salery in fast ladies, fast cars, and good beer, the rest you can waste.
Try and lead your crew with a loose rein, consider they have all been trained and most know and love their job.
As you progress you will from experiance find the point when as commander you need to step in and make decisions also the times when the reins require a bit of tightening and you need to get a grip on the flight firmer than usual. You will develop the art of smelling trouble very early and avoiding it before it hits.
No worries being a captain really... the worst that can happen is you can kill your crew and hundreds of passengers or get fired for your efforts.
Please beware of becoming all the things you hated in your former Captains. It is also better sometimes to be lucky than good.
So Good luck to you and I hope you find being a Captain is a piece of piss, I found the first 25years the worst then it got easier.
