Change form validation error messages

Question

In my theme I'm already using the hook_form_alter to customize the form fields but now I want to customize the validation error messages.

After some research, the only way I'm finding is to write a whole separate function and custom error handling of each form field.

I don't want to reinvent the wheel. Isn't there just a simple way to change the default form validation error so I can get away from "XYZ field is required?"

There are a number of options to resolve this issue:

1. One option is using the String Overrides module to replace the string used to generate the message.
2. Another option is to create a custom module that overrides the validation function for a particular form or field, replacing any error messages with the messages of your choosing.
