You only have so much room up there. Remove less valuable menubar item to make room for your application of choice.

Use the Command key if necessary to drag off menu items or re-arrange them.

Not all running apps put an icon in the menu bar. For instance, MS Office apps don't; neither does Firefox. I'm sure there are many more. Safari either for that matter.
