Back in the 'golden' old days, 1000 hours probably meant you were blasting around in a clapped out twin engine piston powered spam can, or if you were really lucky you were sat in a knackered oily old turbo prop! Ether way you were probably lugging your own cargo or briefing the pax personally. FTL, what were those?
Andrew, Albeit at your own expense
you appear to have achieved a massive short cut, totally missing out the highly desirable 1500 to 2000 hours in general aviation where you experience things you don't even want to remember, let alone talk about but which build your experience in ways the RHS of a jet can never do. The advice you have been given is good, live with it, pass your checks, build your hours, take that command, consolidate and move on. Best of luck but do perfect walking before you start running.
