I grew up in Lithuania, the happiest place in the world for under-30s. It has some of the cheapest rent in Europe and other perks.

• Lithuania was named the happiest place in the world for children and people under 30.
• I grew up in Lithuania's capital, Vilnius, a walkable city with a vibrant culture and nightlife.
• I think Lithuania is a place where the young can truly thrive, and I miss living there. 

Although often overlooked in favor of its larger European neighbors, Lithuania has emerged as a top destination for young people seeking a higher quality of life.
