Enjoy the quiet. Don't let a lack of company stop you from doing that thing or visiting that place.
I took this to the extreme this past summer & did a solo road trip down most of the US east coast, & do you know wanna know what?? I enjoyed almost every second. I can do anything now.
Did this last week, didn’t want to leave. (Disclaimer: doesn't need be to an island… somewhere you expect to feel safe and content will also work.)
Scary? Intimidating? NAH!
Solo vacations = not having to manage the expectations of anyone but yourself = freedom to make the trip whatever YOU want it to be.
Fun! Exciting! HELL YEAH!!!
