I hate this quote/pop advice. For some people location really, truly does matter.
There are irredeemable places, and places that just don’t work for an individual. They key is knowing when it’s a problem instead of just running somewhere random and hoping it’ll fix all your issues.
Personally? I feel way better in sunny, dry climates. My mood improves a ton and I legitimately feel healthier. Right now I live in the exact opposite and I don’t like it.
