Keep you current job, even if you work a bit less at it. Do your flying on nights and weekends as suggested. Pay AS MUCH as you can as you go. IF after you get your PPL, Instrument, CMEL you still want to pursue flying look at the declining number of jobs to low time pilots and you will have to make a decision whether to pursue those or GET your CFII.
Sky had a career that didnt work out for him for many reasons, some out of his control... others probably just bad luck....either way dont let sky's exagerations scare you...while I am sure things like that happen.... look through his BS. HE has an agenda...one that actually needs a voice... he is just a bit militant.
that said.. in the light of disclosure my trek thru this business is not like what I laid out above... I have a military background so bypassed some of that.
Pursue your dream .. it may work out... it may not.... but at least you wont be left wondering... Oh... Sky... made a decision to be married and have a family on salaries that would not support them... certianly a mistake to avoid.
Good Luck.
