Adventures come to those who seek them. One can find big expensive adventures for six months out in the mountains, or small free/low cost adventures like volunteer fire fighting, painting, rock climbing, cooking, dancing, acting, making music, deep friendships.
Our lives are filled with exactly the richness we seek. Travel is just a catalyst to get us up off our sofas and make new friends. Having moved many times, I can assure you that one can do that today without moving.
I've met many unemployed travelers who mope inside all day and watch Netflix. I've also met many hard working people who've lived in the same house for twenty years but live rich, incredible lives filled with small adventures.
