Не выводится список, думаю проблема в добавлении, в цикле while

#include <iostream>
using namespace std;
struct Node
{
	int data;
	Node *next;
};
class List
{
private:
	Node  *head;
public:
	List()
	{
		head = NULL;
	}
	void push_list(int a)
	{
		Node  *uzel = new Node;
		uzel->data = a;
		uzel->next = NULL;

		if (head == NULL)
		{
			head = uzel;
			
		}
		else
		{
			Node *current = head;

			while (current->next!=NULL)
			{
				current = current->next;

				current->next = uzel;
			}
		}
	}
	void print()
	{
		Node *current = head;

		while (current!= NULL)
		{
			cout << current->data << endl;
			current = current->next;
		}
		
	}
	
};

int main()
{
	List name;

	name.push_list(6);
	name.push_list(7);
	name.push_list(8);
	name.print();
	
	
	return 0;
}
