Lets keep this simple...Here's a Tale of Two Brothers.
> The First Brother did the Local FBO/Pay-as-you-go method. Long story short - " It was ALWAYS Something". The Instrument Aircraft was broken, the Instructor cancelled, the money ran out, the weather sucked, the FBO closed, the girlfriend caused problems, the Boss wouldn't let you off work on a given ( important ) day,...It was ALWAYS one step forward and two steps back. Until finally, sick of the lack of consistent progress, he quit flying until he had saved ALL the money required for training, agreed with the Wife that he could quit his job if necessary, agreed with the Boss that he could take a Month off with no pay, and off he marched to a Total Immersion process and left town to go to American Flyers and live in the Apartments they provided. 8-10 hours per day of Ground School, Simulator, and Flying ensued. Three weeks later he had attained his Commercial, Instrument, and CFI . The SAME licenses he had been working on for the past THREE YEARS.
> When the Other Brother ( years later ) said " Hey, if a numb nuts like you can be an airline pilot so can I ! How do I do it? " The First Brother replied " Dump your girlfriend, quit your job, get ALL of the money ( loan, savings, whatever ) in one place... and GO for it ! "
Six months later this Brother had gone from Zero time to Comm. , Instrument, Multi, CFII-MEI and was immediately employed as a Flight Instructor at the school he trained at.
In short: Get all of your TIME, money, resources and responsibilities wrapped up and in one cohesive place and dive in. As opposed to wasting any and all of the above going at things piece-meal.
Just speaking from experience...
GOOD LUCK!

P.S.- I saved the additional money and never did the CFII/MEI. Just did primary Flight Instruction for 600 hours and got my first airline job. That was in a VERY crappy hiring environment, as opposed to now.
