You aren't doing anything wrong; you just need to have a better understanding of depth of field and what aperture to use.
A very vague general guideline is this (From Bryan Peterson)
f/5.6 and lower = good for isolating your subject from it's environment.
f/8-f/11 = use when you don't care.
f/16 and higher = use to get things in focus from front to back...to tell a story with multiple elements in the image...close, middle, and background.
This explanation is really helpful to understand me to choose f-stops.
