Are hitters in your opinion too selective at times?

Joe from Canada inquired

My response:

Generally, no. It's preferable to take a pitcher high in the count to run up his pitch count, but the goal for the hitter is still to get a good pitch to drive somewhere HARD.

Hitters are taught to narrow the width of the plate from 17 inches to the middle 10 inches, and expand back out to 17 inches when there's 2 strikes in the count. They recycle their approach in each at bat usually with the minimal idea that each pitch is their pitch, and expect fastball and adjust to the curve.
