Maybe those people have other priorities/commitments in life. For example, they may donate A LOT of time, tutoring underprivileged students, working at the local abused women's shelter, transporting dogs to no-kill shelters, delivering Meals on Wheels to seniors who cannot get out but who light up when they see them at the door, or maybe they are training puppies to progress to the training for special assistance dogs.................there are all sorts of ways people may choose to spend their time or make commitments. Or, maybe they just are not interested in traveling. Or maybe in a crazy world, they just love the comfort/peace of their own home....the familiar. I would have no interest in going to the Super Bowl, likely not even if someone gave me tickets (sports fans would think "what? is that lady nuts?")
We all have different interests and sometimes at different times/points in our lives.
Let's not judge anyone. Just relish in the tapestry of life that is created by our friends/associates that make it one big colorful world of different talents, interests, etc.
And, think HOW CROWDED places would be if EVERYONE wanted to go there. Note how many times people post/complain about crowds.
I have personally traveled A LOT....all seven continents (repeats to Europe), most of the US states, VI and BVI. Besides Antarctica, our favorite trip of all time was 5 nights we spent on our second visit to the (now destroyed by a hurricane) Caneel Bay Resort on St. John. Woke up, walked the beach, snorkeled, went to brunch, sat on beach under palm trees, snorkeled, sat on beach, watched boats from covered balcony on the beach, went dinner......repeat, repeat, repeat.........relaxing and totally wonderful....never left the resort. We are normally go/go/go on touring vacations, but I learned the art of relaxing on that trip, and there is absolutely nothing wrong with that art :)
Two years ago, after returning from a second trip to Asia, we decided to adopt a puppy and now he is a big focus of our lives. His 2nd birthday was earlier this week, and he knows which ball is his "birthday ball" when I tell him to go get it :) :) Lucky for anyone reading this, I am not able to post photos......I am a doggy mom :)
We took a short National Geographic trip to the Sea of Cortez earlier this winter, but I just cannot (yet) get excited about another trip. Oh, the catalogs come....6 and 7 a day (seriously), and we will travel again.....more places we still want to see....but I am just not excited to plan anything right now. Taking a break. Nothing wrong with that....other priorities right now. We may travel in another year, we might wait 2 or more, but we will not force it until we are excited to do it. If Caneel were rebuilt to its original form (and likely it will not anytime soon), we would be there in a heartbeat.
So, Mike to answer your question. They have other priorities or they simply just are not interested right now. Accept that and them.
