I'm thinking of deciding that I won't let my son pursue acting full-time
What will happen to your son if he can't pursue acting full-time?
I think he will be angry with me probably.
It is good to make decisions for your kids. You should be honest and open to them about it and maybe let them do it part time.
Life isn't fair and I want to use my privilege to keep him away from bad in life.
Acting might not be for everyone but you should not ruin your children's dreams. Just make sure you are thinking about him and not yourself like you are jealous.
