Just a few weeks ago for me. Before that, it had been about 5 years. Before that, it was a couple of times per year. What the most recent trip made me realize was that we all really need to take a step back. It was hard to be in vacation mode and it felt like by the time I could let myself relax, it was already time to get back to reality. 17 years is far too long. It’s not good for your mental health. Please take some significant time off and just enjoy it.
