I have been around a bit; in fact. I live abroad.
I enjoy the travelling. It helps if you can get in the mindset that the travelling is actually part of the holiday. Packing can be a game, arriving early at the airport and treating myself to a drink or even a nice meal, as I won't be driving, trying perfumes at the duty free shops, people watching.
Putting the work in in advance, preparing well by writing lists. Downloading the necessary apps, reading up on the sights to see. This all reduces the stress but helps you to get excited and look forward to it rather than be apprehensive about the strange situations.
I watch a lot of travel documentaries on YouTube, too. But sometimes I just like to be somewhere else.
