Write a Letter to Your Future Self at Neks
Paid
One of the best things I did in Ljubljana. At Neks, a cozy lounge bar near the old town, you sit down with a drink (I had a matcha latte), write a letter to your future self, and seal the envelope with wax. Neks keeps the letter and mails it to you two years later, which makes it a lovely, low-key way to spend an hour.
