If you are stuck in life travel to a place you have never heard of.
I've been traveling for quite a few years. Each time, somehow, something happens to me. Sometimes, it's funny; sometimes, it's intense; usually, it feels like it's straight out of a comedy show, and it's never easy to shake off. I often ask myself, "What was I thinking at that time?" I frequently don't learn the lesson. I've experienced travel in many ways, shapes, and forms. Sometimes solo, sometimes in a group of 18. I've slept in dormitories and stayed in five-star hotels (by mistake). I've done self-guided tours and paid for luxurious ones. I often travel for business, and once, friends told me that we crossed the border after a party (again, a mistake, and what a mistake). So I have some suggestions for you, to make things more interesting.
Do you run from or towards something?
I believe there are two modes of traveling: run from or run towards. If you "need a vacation," if you need to escape the routine, if you need to recharge, revigorate, and "read that book that you don't have time to," then I think you are running from something. And there is no problem in doing that. In this way, you travel to remove yourself from your routines, get the pampering and attention you don't ordinarily get, and ideally do fun things instead of work things. So you travel to where it is easy. This is called a vacation. I do vacations, but often, I don't come back with a story.
The other way is to run towards engagement and experience. You travel to discover new things, have fresh experiences, embrace an adventure with uncertain outcomes, and encounter otherness. You move to find yourself through pleasures and challenges that you don't encounter at home. This type of travel is a form of learning; out of the two, it is the one I prefer.
Small and frequent works with running from something, long and rare works with running towards something. Frequent city breaks to different cities can keep things fresh. Two weeks of travel to a remote place and slowly returning to civilization is very humbling.
