My Shepard finally cuddled me?!??

Not sure if I should be concerned or ecstatic.. my boy Nash is about 1 1/2 and has so much energy. He never really settles down, so he gets crated at night. He’s starting to get calmer and this was a nice little treat! I hope it just gets better from here since he was such a hard puppy to have. What age has everyone’s dogs began to settle down? (He is intact, I do not plan on neutering him)
