What holiday?

I did that once. Had planned a trip to London with my girlfriend and then we broke up. So I went alone. Had a great time walking around London alone for 10 days. But that was a long time ago. Also I’m the kind of person who doesn’t mind traveling alone.

Most of my holidays are always on my own
Dont have to rely on anybody else and can do what I want when I want

I wish. It's not really feasible for me at this point. :)

Traveling alone can feel exhilarating when done properly. Just some things to consider
The location
Understanding the reputation of where you are going.
Staying aware of whatever dangers are common there and of course as a woman in general.
Be smart and understand the laws and customs of where you visit long before you enter their land. Maintaining a confidence realistically of your abilities. Spontaneity is wonderful but planning ahead is a good idea.
Important to let people you care about know where you’ll be that day, if with anyone etc Check in often. Immerse yourself in the culture of where you are. Taste the foods, visit the stores, any beautiful views or historical locations. Be friendly with those around you. You want to be smart and safe but you also don’t want just any vacation of pool lounging and drinks at a bar.
