Year of 2016 is coming to an end and 2017 is the year I will start my IFR training. I'm pretty excited about it - enough to be jumping the gun as I don't yet have a concrete "start-to-finish" plan, other than to start reading lots of book material on IFR before the instructor training. I'm (still) a low time pilot and I have never witnessed anyone fly IFR ('xcept youtube). So I wanted to ask this: for anyone that started their IFR training but did not complete it, or took a lot longer than initially anticipated, what were some of the reasons/factors? Thanks a lot for any info.
