"When you've had 450, 500 games in the Premier League you keep doing what you've always done, you keep doing what you think is right." Moyes told British media.
"You try not to get too caught up in the whole thing. I don't think we can do. If we were going in blasting every player, I don't think things will necessarily get any better," the former Everton and Manchester United manager added.
"We are trying to train correctly, trying to put into practice what we think will be good for them. So we try to follow all the right things you would do when you're in a difficult situation. And we are in a difficult situation."
The 53-year-old acknowledged his Premier League return has been less than impressive.
"It's damning, I agree," Moyes added.
"It does make me feel lousy, and I do. I don't feel good about it but you've got to take it. I probably spend Saturday night, and quite often, in a darkened room somewhere.
"Sunday gets a wee bit better, but not much, and hopefully by the time Monday morning comes, you are ready to go again.
"You've got to get it out of the system and you are up and running again. And I'll do that again on Monday."
Sunderland, seeking their first league win of the season, travel to 10th-placed Bournemouth on Saturday.
