Congrats! For me, one of my two proudest moments in my aviation career so far has been getting my IFR rating. It's what separates you from the fair weather pilots (literally) and being able to go on a foggy morning while everyone else is stuck waiting for visibility to go up. For me, I also felt more like a "real pilot" shooting approaches and working constantly with ATC being in "the system."

Have fun on the commercial since it, I think, is one of the more "fun" certificates to get. Power off 180s are a blast!

Good luck and congrats!
