With an Instrument Rating, you’ll be able to go wherver you want, but now more often. You’ll no longer be constrained to flying in the most optimal of weather conditions, or have to take a back seat to commercial jet traffic. This license will allow you to fly under a new set of flight rules in which a controller will guide you to your destination over the radio.  The instrument rating will also make you a more advanced and safer pilot and will teach you to fly the way commercial airlines operate.
