Depression is mainly alleviated by doing something productive almost every day. That way, your night feels good because you got something done, and so does your next morning.

  void reverse_list(head) {
    struct node* current = head;
    struct node* last = NULL;
    struct node* next;

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