What do you think of traveling alone?

Hi everyone,

I wanted to post a question on here that asks what you think about traveling alone both in the US and globally. As many of you may know from my previous questions, I am a gay, single guy who loves traveling, photography, and writing. Anyways, since I recently discovered these passions I have a goal to visit all 50 states and travel around the world before I die. Its basically my big bucket list!

Anyways, today I traveled about an hour from where I live to a town that has an old downtown area with a westernized theme and an art district. I absolutely enjoyed it and got to take lots of photography of the various art statues around town. The best part about it was that I got to travel alone and experience the area by myself?

So I wanted to know what does everyone on here think about traveling by yourself around the US? Now as far as traveling around the world goes I know there are group trips you can schedule online with other solo travelers to foreign countries. Would you travel by yourself if given the possibility? I like it because you get to do what you want. Also, how do I make myself fit in when I do travel to these places alone such as on a group tour or in a museum? What should I do to overcome the self consciousness feeling I sometimes get about when people notice that Im alone?
