• Keep (some) secrets. When poker legend Doyle Brunson met his wife Louise at a country-and-western club in Texas in 1961, he told her he gambled for a living. And she accepted him for who he is. "Love is the most important thing," says Louise Brunson, 78. "You have to love your spouse more than life itself."
The Brunsons, who live in Las Vegas, have stood by each other through some serious trials in their 47 years of marriage, including the death of a daughter and an armed robbery of their home, during which they were tied up at gunpoint.
"You have to go forward, you can't go back," says Mr. Brunson, 76. Even so, the Brunsons don't share everything. He doesn't discuss his business with her. "I have won and lost millions of dollars without her knowing," he says. Ms. Brunson says that's just fine with her. "I have my own bank account," she says.
