Can I tell my parents that I want to be a lawyer but actually I want to be a clown?
Do you want to find out what they would think?
I want to know what other people who are happy with their lives do
It is good to want to follow your dreams but you should share that with your parents. Otherwise they will feel betrayed.
If they don't react with disappointment, I'll know that I can follow my dreams and tell them later.
Your parents are just showing concern for your future and they want you to be financially secure. You should take their advice into account but also remember to follow your own above theirs. You future is only in your own decisions.
