All sterling advice above. Learnt a few things, thanks all. I might be a bit late adding this, but WTH.
Personally, I think the most important thing other than don't fly without a rebuy, is quite simply enjoy yourself in the simulation/game*
It will all come together eventually & quicker than you think. Instead of grind, grind & more grind.
Be patient too, you won't be triple elite & zipping around in a corvette or cutter within a few weeks.
Just, enjoy, it, for, what, it, is. Never take it too seriously
& welcome, as a relative newcomer here myself. I've found it to be a good resource for picking up the finer points of a complex simulation/game*
(* - I'm still undecided what to refer to it as.)
