I urge you to travel. As far and as much as possible. Work ridiculous shifts to save your money.
Go without the latest iPhone. Throw yourself out of your comfort zone. Find out how other people live and realize that the world is a much bigger place than the town you life in.
And when you come home, home may still be the same, and yes, you may go back to the same old job, but something in your mind will have c h a n g e d.
And trust me, that changes everything.
In a few days, I will be leaving for Tallinn/Estonia with a day-trip by ferry to Helsinki. We will explore the local cuisine of both countries, stroll through the Christmas market (started 18 Nov 2016) in Tallinn, and be amazed by some of the heated streets of Helsinki.
