Find another pattern -- there are thousands of freebies online. One of the best is the classic Marsan Watch Cap, found here:

Ignore how dopey it looks on the retro figurine. This is a warm, beautiful hat that knits up easily and looks good on men and women. Note that there's no gauge on this one either. But the author gives guidelines for adjusting it for different sizes, and the ribbing is extremely forgiving. I often borrow the one I made for The Old Man, whose head is considerably larger than mine -- no problem.
Another suggestion: look at Ann Budd's "Knitter's Handy Book of Patterns." Her basic cap pattern can be made in any gauge with any yarn to fit any size from infant to large adult. And you can make it in plain stockinette, ribbing, you name it.
There's no point in slogging through a poorly written pattern, unless you want to use it as an exercise in swatching and determining your own gauge (not a bad idea).
