MENLO PARK, Calif. — By almost any definition — except his own and perhaps those of his neighbors here in Silicon Valley — Hal Steger has made it.

Mr. Steger, 51, a self-described geek, has banked more than $2 million. The $1.3 million house he and his wife own on a bluff overlooking the Pacific Ocean is paid off. The couple’s net worth of roughly $3.5 million places them in the top 2 percent of families in the United States.

Yet each day Mr. Steger continues to toil in what a colleague calls “the Silicon Valley salt mines,” working as a marketing executive for a technology start-up company, still striving for his big strike. Most mornings, he can be found at his desk by 7. He typically works 12 hours a day and logs an extra 10 hours over the weekend.

“I know people looking in from the outside will ask why someone like me keeps working so hard,” Mr. Steger says. “But a few million doesn’t go as far as it used to. Maybe in the ’70s, a few million bucks meant ‘Lifestyles of the Rich and Famous,’ or Richie Rich living in a big house with a butler. But not anymore.”
