What is the easiest way to implement your own functions that are used throughout a large project?

Question

I want to create a set of functions that make life easier. I use them in about 60% of all project files. I wonder what the most effective way to include them in the project.

I am thinking of creating a single file, which they include, and including this file in every file in which I need them. On the other hand, it would be great if I could only include this once in a prominent place so that it was available throughout the project. But I don’t know what place it could be. I am not sure, but I think it is impossible. Or am I mistaken in this assumption?
