The instrument rating will probably be the most demanding and rewarding rating for a pilot to obtain. There is no room in the Instrument Flight Rules world for sloppy pilots or weak airmanship. The instrument rating you ultimately obtain is a “professional rating” the same rating an airline pilot has along with all of the responsibilities and even more of a work load if you are flying “single pilot” IFR.
The whole purpose of an instrument rating is to be confident and proficient in IMC and working in the ATC.
