Your project layout should be

./main.go
./myProject/myProject.go

then run the program with

$ go run main.go

If you comment out lines 11 and 12 of main.go, then the program will execute correctly

main.go

package main

import "fmt"
import "./myProject"

func main() {
	s := myProject.NewPerson()
	fmt.Println(s.Name)
	fmt.Println(s.DOB)
	fmt.Println(s.GetSSN()) // This line will return the proper results
	fmt.Println(s.superSecretFunction()) // This line will error out
	fmt.Println(s.ssn) // so will this one
}

myProject.go

//./myProject/myProject.go
package myProject

type Person struct {
	Name string
	DOB  string
	ssn  string
}

func (p Person) GetSSN() string {
	return p.superSecretFunction()
}

func (p Person) superSecretFunction() string {
	return p.ssn
}

func NewPerson() Person {
	s := Person{}
	s.Name = "Adrian Zankich"
	s.DOB = "11/05/1955"
	s.ssn = "xxx-xx-xxxx"
	return s
}
