18th century writer Samuel Johnson once said, “When a man is tired of London, he is tired of life; for there is in London all that life can afford.”
Much has changed in London since the 18th century, but the sentiment of Johnson’s statement is perhaps more apt than ever. London has developed into one of the most exciting and vibrant cities in the world. It’s steeped in history, diversity and regardless of where your passions and interests lie, you’ll find an outlet for them in this wonderful city. If you’re preparing to live in London, here’s a little teaser of what’s in store and what to look forward to as a new Londoner.
