The OP needs to define what he wants to do flying-wise, and obtain the papers and the plane which matches that mission profile.
Nobody else can tell him how to stop himself getting bored.
IFR flying in itself is fairly pointless. What is great about it is the way one can use it to go A to B, while sitting comfortably in sunshine (above any clouds) and not worrying about ATC clearances into CAS, and potentially having great views.
IFR flying is actually same as VFR flying would be if one did not need a clearance for anything. If I fly from the UK to say Greece, IFR, I go the same way as I would go if I was going VFR. But I can't go VFR on that route because there is some CAS into which I would never get a clearance....... the result of totally meaningless restrictions, implemented for totally arbitrary rule-based reasons.
