I have always been the type of person who gets antsy staying in the same place too long or doing the same thing. I need challenges; I need change. I'm not a big time planner. I usually only have hotel reservations when I go somewhere new or I will get tickets to something in advance only if necessary.
Long term travel is far different than short term travel. Even if you travel for two months a year and then go home for ten, it's not long term travel. I've heard from many people who want to do what I'm doing because they base the idea on their short term trips.
Here are some things I learned:
1) Be realistic about what you are physically capable of. I'm 61. In my mind i'm 30. Every now and then the body reminds me of the truth. Give yourself rest periods. Let your mind and body rejuvenate. Pace yourself. Travel slower. Take your time.
2) Don't make too many plans in concrete. Be willing to change destinations, hotels, travel goods, etc. I do this all the time.
3) Occasionally, treat yourself better than usual--a nicer hotel, a really good meal, etc.
4) Go home occasionally. I go "home" every three months to refill prescriptions, see the doctors and dentist, see friends. It's not really going home since I'm in a hotel. I am getting bored of the area and now spend little time there. But traveling through the U.S. is easier and more familiar to me than most foreign destinations.
5) Take something(s) with you that will make your travel life more enjoyable. For me it's an immersion heater and cup. I like a hot drink first thing in the morning and sometimes in the evening.
6) Do what interests you. Just because a guidebook's author likes something or people on this forum insist you do something only do what you want. It's your time and your money.
7) Don't be afraid to ask your hotel for extra's if you need/want them: more towels, a fan if it's warm, ice if you need a cold drink. Don't worry how you will be seen. You are a paying customer. ( Of course, be polite.)
8) Find things that rejuvenate you. For me it's getting on a train or a plane. It's the excitement
of going somewhere new. And on a train I get to look at the scenery. I believe the journey is as important as the destination.
9) Pack light. I'm not talking about trying to join the under 5 kg crowd. Just realize the basics, especially toiletries, can be found almost anywhere. Be flexible with soap and shampoo. If what your hotel offers isn't too offensive to you, use it. I carry a bar of fragrance free soap to use when what the hotel has is too fragrant or will make my hair smell like a tossed salad.
10) Learn a few words in the local language. . However, nowadays, especially in much of Europe, if you go to places that get FOREIGN tourists you will find people who speak some English. Don't assume. Be polite and first ask if they do.
By the way, I'm not going to stop traveling. I have a planned trip to Sicily and Southern Italy that I am looking forward to.
