how do i call for a string variable from another script?

So let's say I have a script called "GameMaster" Here is the code in "GameMaster"

 public class GameMaster : MonoBehaviour {
 
 public string  thing = "Hello World"
 
 }

And then i have a script called "StringGet"

 public class GameMaster : MonoBehaviour {
 
      //This will be set to the game object the script is attached to
     // Named "gm" for simplicity
     GameObject gm;
    //Name of script in our case "GameMaster"
    // Named "gms" for simplicity
    GameMaster gms;
 
 
     void Start () {
        // Name of game object that sccript is on
         gm = GameObject.Find("GameMaster");
       // Now actuallly finding the script
         gms = gm.GetComponent<GameMaster>();
 
        }
 
         void Update () {
            // Now we go "Gms." and then the name of the variable
              debug.log(gms.thing);
       }
