why is family support so difficult when it comes to poker?
I agree family (and friends) can be difficult. It might be possible to ease this friction if you can find a way to make a relationship to something your family (or friend) understands.
Myself, I used the stock market. I explained that the stock market is a form of gambling. Like poker, the stock market relies on making mathematical predictions. Stock market is also swingy and there are not any guarantees. Once I used the stock market example my family started looking at poker differently and are very supportive.
