Something is natural and thus becomes natural when you do it often enough.
To change what is natural has to be a result of repetition, for the new action to be felt as natural.
If you always slog, hit out and don"t think when you bat, then this is your natural game. To change it, you would need to start batting responsibly until that became natural.
