There are a lot of ways to determine which locations are best for you to live in and/or travel to. I like to keep things simple though, esp for those who have trouble making decisions.
One simple way to seek out compatible locations is to look at your First Name. The 1st Vowel of your First Name is your Soul Vowel. This is the energy that people may keep to themselves. It's what makes you feel comfortable at a deeper level.
Every letter in the alphabet vibrates to a number in numerology. Heading to locations that share your 1st vowel energy may make you feel "at home" with the locations. This can apply to countries, states, cities, islands, etc. You can then visit www.numbeo.com to learn more about locations around the World, esp if you choose to stay awhile.
