Back in 2008, I went for a very long holiday. 3 weeks in total. In fact the original plan was for me to go for 2 weeks, but I decided to extend for another week because it was really good and 2 weeks was just not enough. My life was so much different then. I had everything more in order, and disappearing for 3 weeks was not difficult at all.
In addition to that, data roaming was not a norm, as such going on holiday is so much more fun as I am completely disconnected from the life at home. And I could enjoy my break so much more. Maybe I should do that again during my next break. Digital detox!
