It is impossible to talk/explain anything to non poker playing person how it different from general gambling, they just cant figure it out and if you don't want lose your friends, just don't talk about it
Talking about family, its even worse, its like telling your parents that you are drug addict. There are several exceptions when your parents is ok about it, but it is rare. And about other people who asks where your money come from I would say from doing some Internet stuff whats is to hard to explain...
Of course everything changes when you win in sunday million and in a day, everyone loves you, even your exes and other people that ignored you in the past starts to love you and in one moment poker is a skill game and everyone wants a piece of you.
