Whilst rudestuff and Negan make a good point, it's not very helpful. Ex CTC/L3 cadet here, made the mistake of paying a fortune for my training.
Don't get me wrong, the standard of training is superb. Just not worth the money. My advice to you....hit the ground running. Ground school is a slog. Put the time in, don't fail any exams and work hard. It'll all be over in 6 months.
Having said that, take time to yourself. Have Sundays off, go to the pub etc.
Keep your head down. Keep in mind all your instructors (ground school and flight) will contribute to a final report that's written about you which your future airline may read (few of my mates had things in their report they weren't too happy with).
Don't write a blog..no one cares about your 'road to the right hand seat'. Spend that time studying or down the pub.
Be realistic. Leave your current job on the best terms possible. Chances are you'll be back there once you go into the hold pool. You don't know how long you'll be in there. Walking back in to my office job (where I was welcomed with open arms) and earning a reasonable salary has helped me massively.
Finally (cliche, but..) enjoy it. The time I spent in New Zealand was the best of my life. You cannot beat flying a 172 round some of the amazing scenery out there.
