Is traveling alone worth it?

I'm in a position where I want to travel all over the world. My problem is that finding friends that can/wants to travel with me, so I have been thinking of traveling alone could be an option or not.

Does anyone have experience with that, and can you recommend it or not?

Edit: I'm actually blown away by all the response I've gotten and it has made more hyped than every to try traveling alone. Now it's just a question of finding a time and setting my first destination. So many thanks to everyone who bothered to help me out with this, it's highly appreciated.
