I am never going to lie to my parents again.
I will never lie to my parents again.
Which one is correct? ‘Will’ or ‘is going to’? Because as far as I know, going to is used to talk about situations that I have already planned on doing, and will is used for talking about a decision that I have just made.
Here, I have made a decision of never lying to my parents ever again because of the consequences of my actions that put me in trouble. So what form should I use?
Also, another example:
I am going to make my parents proud when I grow up. Vs I will make my parents proud when I grow up.
Here, since I don’t have an exact plan about what i would do to make my parents proud when I grow up, but I just feel like I would do anything just to make them proud, would the use if “going to” be unnatural?
