What worked for me was travel - long term travel, working overseas. Then I became interested in the linguistics, art, geography and history of other parts of the world. I think I could pretty happily live almost anywhere now, and notice and value the good things about my environment a lot more than I used to, having gone without. Things like art galleries, museums, good cinema, interesting bars, global food.
Likewise. I was fortunate to live and travel through South America and Southeast Asia through my teenage years since my father took overseas engineering jobs. I cannot begin to express what traveling, and more importantly, immersion, will do to your vision and your priorities. It's a wonderful world out there.
