Please imagine someone's parents are giving some advice to their son. The father wants to say something that feels it would be very beneficial for his son. (For instance: continue his education.) Which one of the sentences below would work in natural English:
1) Do it; it is to your profit.
2) Do it; it is to your benefit.
3) Do it; it is to your own good.
Added: What the son would say in reply when he thinks contrary to his father?
1) It has no profit for me.
2) It has no benefit for me.
3) It is not in my own good.
I wonder if you could let me know about a better option, if you think that there is something wrong with my made-up sentences and if you think that there is a better/more common alternative in natural English that can make a better sense.
Thank you in advance.
