Firstly, I would ignore this sort of comment.
If you can get anything instructing part time then do it, just don't do it for too long, same as skydiving, good to get your first couple of hundred and consolidate but make sure you make a break up North when you can and get into the real stuff, I love it, and where I am at the pay is quite good.
I have been an instructor, charter pilot (mainly in the NT) RPT, jets. The most satisfying was instructing. The most unsatisfying is my current job. It just pays the best though. The one that is a short term career would have to be charter pilot, there is no future or money in that type of job.
You, xelophab, need to sit back and decide where in the industry you want to be. Instructing is very rewarding, and if you stick with it and are any good it can provide a living, so can most other directions.
If instructing is not your long term goal, well, I would suggest don't venture there to start with, do the potential students a favour and be a charter pilot.
what ever you decide to do, if you are keen enough you will get there, you may need a few part time jobs to support you along the way.
Good luck, choose your flying training organisation and instructor carefully.
