Rather than worry about how you can get through the ranks as quickly as possible, why not focus on enjoying the rank you're in?
Work on establishing personal competency in your trade, use your initiative when appropriate, and before you know it, you'll be nominated for PLQ. Then it all starts over again, sort of. You'll work on gaining competency as a Leader/Section 2IC/Commander, in addition to your competency as a soldier/rifleman, and before you know it, you'll be nominated for SLQ (or whatever).
What I'm saying is that if you are only looking for the end state (Sgt, WO, RSM, CO, CDS), you'll spend your whole career focussed on something you want to attain, rather than enjoying what you have attained.
As a Private, I loved the lack of responsibility and the idea that I just had to 'do', and not worry about planning, leading (formally), etc.
As a Corporal (non-2IC/Commander), I loved not getting all of the sh*t jobs, yet still avoiding most responsibility.
As a Cpl (Section Cmdr/2IC), I love the responsibility of command, and the idea that the position of Sect Cdr is the only leadership position in the CF where you lead soldiers - all other Leaders lead other Leaders.
You get the idea.....Ambition is good, but enjoy where you are....even if that is 'applicant'...that was kinda fun too!
