Esty likes to say that although she grew up in NYC, her first visit to the Statue of Liberty was a couple years back, when visiting New York as a tourist.
People are often more excited about attractions in other cities, because of a certain novel allure and unfamiliarity. When we travel to new places, everything is fresh and exciting, and we're more open to new experiences and adventures. In our own hometowns, we may take our surroundings for granted and feel like we've seen it all before, leaving us unenthusiastic about local tourist attractions.
In a similar sense, it is not uncommon for a convert to Judaism to be even more enthusiastically observant and meticulous than their born-Jewish counterparts. The convert has a special place in the eyes of G-d, because of them choosing Judaism, on their own initiative, with the inspiration coming from deep inside.
We can all take a page out of the conversion book. When a Jew chooses to increase his or her Jewish observance, even in the smallest way, one more visit to Synagogue, Shabbat candles lit, Teffilin wrapped or charity given, G-d’s reward is commensurate (not based on the deed, but) with the effort and enthusiasm invested “Lifum Tzaara Agra” (Avot chap 5) .
So while yes, we ought to feel right at home in our Judaism, when it comes to enthusiasm and curiosity, we should channel our inner tourists.
