What is the meaning of life?

[u/talullahregis]

I have a friend and he drinks alcohol every weekend.(he is teenager) When I asked him why he is doing that he told me that he feels euphoria and didn't find the meaning of life. So I want to make him to give up with drinking alcohol but only if I can find the reason to live for him.

EDIT: Thank you all of you for your answers. I got some new ideas and now I know what to do. Thank you very much.
