Main navigation menu options for lengthy names

Hello,

I am wanting to have my main navigation to support up 7 items (ex: Home, Contact Me, etc.) I’m coming across a challenge that the category names (ex: Problem Solving) is bleeding outside of the Main navigation area and into the body of my site.

I would appreciate assistance in understanding what options are available to solve this. I’ve tried reducing the font size but that looks out of place and the spacing between two words like Problem Solving causes it to still run over into the site.

Thanks.
