Rob - what can anybody add to that, it's both brilliantly put and true !
So listen-up all you wannabe's and take honest stead from those of us who have travelled the very rocky road that is aviation before you. For we do not want you to suffer the many trials and tribulations that beset our own careers - and hence much of the reason why PPRuNe exists, i.e. to put something back - and would instead have the journey both clearer and more honest ( e.g. w.r.t. your expectations and for those who would sell you useless & unnecessary courses, to say nothing of exposing the tactics of certain scurrilous employers, i.e. all - well certainly a fair few - tremble at the thought of being 'exposed' on PPRuNe ).
Veritably there is no hiding place for the aviation charlatans of this world, as they are now too easily exposed and, as knowledge IS POWER, we implore you to imbibe your fill from the fountain that is PPRuNe !
Ps. My waxing lyrical hat, in the style of Henry V(?), is now off - but I hope you get the point !
