The more places you see, the more things you see that appeal to you, none of the places has it all. The more you see, each place has a smaller and smaller percentage of the things you love. This drives you subconsciously to keep looking for a place, not that is perfect, but just for a place that is just right for you. But the curse is that the odds of finding just right that place gets smaller, not larger, the more you experience. So you keep looking even more, but it always gets worse the more you see.
This is part A of the curse.
The more you travel, the more numerous and profoundly relationships you will have. But the more people you meet, the more diffused your time is with any of them. Since all these people can not travel with you, it becomes more and more difficult to cultivate long term relationships.
You keep traveling, and keep meeting amazing people, so it feels fulfilling, but eventually, you miss them all, and many have all but forgotten who you are.
And then you want to make up for this by staying somewhere long enough to develop roots and cultivate stronger relationships, but these people will never know what you know or see what you have seen, and you will always feel loneliness, and you will want to tell your stories just a little bit more than they will want to hear them. It gets worse the more you travel, yet travel seems to be a cure for a while.
This is part B of the curse.
