heyo, I've been traveling for ~15 years now, been to ~30 countries so far and it continues to be extremely rewarding and fuuuun.
I've had travel partners now and then, though I prefer solo traveling for the absolute wide-open "guess I'll go walk toward that mountain in the distance for 4 hours" and "guess I'll try 8 gelato flavors today" type of freedom that is very difficult to attain traveling with others.
I'm traveling solo in Matsuyama, Japan right now. Today I decided on a whim to take a train to Imabari, hung out at a temple, found my favorite yuzu ponzu sauce at a grocery store, spent a couple hours at a public bath, practiced some Japanese, stopped at a random yakitori restaurant on the way back, talked in terrible Japanese with the staff who were very kind and gave me a free shirt I'm wearing now! Pictures of the amazing food here.
I love solo traveling so much I keep doing it and talking about it, nothing else really compares for me. it's certainly worth looking into and If you have any specific questions or concerns, I and the travel community are here as resources for anyone interested, so feel free to reach out. Apartments, healthcare, jobs, transportation, budgeting, whatever, I'm happy to talk.
