Those with aspirations of unfettered wealth look for clues everywhere. From top schools to unique talents, they build profiles of what it takes to become absurdly wealthy ... as though the process can be blueprinted. Well, if you're looking for answers, the Forbes 400 list is a great place to start. If anyone has mastered the art of making money, it's this collection of billionaires. They have the answers, and you are ready to learn.

A look at the lives of the Forbes 400 implies that the most important attribute is the ability to sift through ambiguity. Contradictions abound, meaning that shades of gray hold the answer to your burning desire for riches. Should you go to a great school? Well, yes ... but only if you're going for an MBA and plan to work for a major financial firm. But, you can still go to an Ivy League school if you're not studying finance but join Skull and Bones. Of course, dropping out of Harvard can be a great way to launch a career in the technology field.

It's tricky. There are no easy answers. But, the road to billions is littered with the corpses of aspiring magnates who thought it wouldn't be difficult. So, don't just read the seven attributes after the jump. Understand them. Read them twice. Then, your future financial situation will be assured.

Or, you can just do one of those chain e-mails and wish for wealth.

According to Forbes, Bill Gates of Microsoft (NASDAQ: MSFT) is no longer the richest man in the U.S. The honor now belongs to Warren Buffett, the head of conglomerate Berkshire Hathaway (NYSE: BRK.A). Buffett is worth $62 billion to Gates's $58 billion.

This says more about the shift in the American business landscape than it does about anything else. The Berkshire Hathaway stock is up 30% over the last year, while Microsoft's is flat. Since Berkshire owns an insurance company, it would make sense that the financial crisis would hurt its value, but Buffett has stayed away from the investments that have hurt other companies.

Microsoft may be a safe investment now with its large cash position and steady income from Windows, but it is probably no longer a growth stock. Microsoft software runs on 95% of the world's PCs and many of its servers. That leaves the question of what the company can do to expand rapidly again. The answer may be that it can't.

Buffett's company is in more than a hundred businesses. He can make the argument that diversification is the foundation of a successful corporation. The firm's operations make everything from uniforms for police to concrete block, roofing systems to fabrics. Berkshire also owns large parts of companies from American Express (NYSE: AXP) to Wells Fargo (NYSE: WFC).

The new Forbes ranking shows that a large bucket of good investments trumps owning a piece of one successful company in a market that is no longer growing quickly.
