Yes, I'm working on the instrument rating right now and am doing well. My instructor said I've picked it up very quickly and I can do IFR basics pretty much by second nature now. Approaches, holds, etc require attention but I can hold an ILS and find an intersection without much stress. Studying for the written is some of the most boring reading I've ever done. I practice all the time on flight sim too. Sometimes flying is all I can think about
