At times, it seems like the entire tech universe orbits around just one company.

Nothing is bigger than the Big Apple. Not only is it the largest stock holding for individual investors, but also for hedge fund managers and StratFI clients, too. Apple is now bigger than Exxon Mobil by market capitalization, and is the most highly valued company in the world.

That kind of gravitational mass attracts significant influence. Apple now represents 4% of the S&P 500 index. Last year, shares rose a stunning 40%, contributing a full 1.5% to the return of the popular benchmark. As investors put money into index funds, they are often buying shares of Apple.

Without Apple, the tech world would be a much less exciting place. A recent Zero Hedge article notes that “blended Q1 Y/Y EPS growth for the Information Technology sector is 0.7% [but] excluding Apple, the blended earnings growth rate for the sector would fall to -5.1%.”

Apple is pretty much holding the tech sector together right now. So why not hitch a ride on a rising star?

Make money, have fun, be excellent.  This is all you that you really need to know to have a sustainable and fulfilling career.  So simple, yet many people lose sight of this. 

Let's face it, making money is the reason why most of us go to work. If your business isn't generating cash flow and paying the bills, you won't be in business for too long... 

Having fun is about maintaining positive relationships.  This attracts new customers and makes work pleasant and joyful.  Lose sight of this and you'll eventually burn-out. 

Being excellent involves becoming your own best competition.  It is about staying focused and engaged in your work, and always striving to make the world a better place.  Remember that you can't grow if you aren't willing to stretch a little! 

This is a package deal - each part makes the others possible.  Make a promise to do these three things every day and watch your life flourish.

This has been a big week for Apple, as it officially announces a watch that connects to the popular iPhone. Apple is now the largest publicly-traded company in the U.S., bigger than even Exxon Mobil. Nonetheless, I'm more of a Google fanboy.  Apple has a lot of very smart people doing cool things. Google has brilliant people doing things that leave me in state of complete awe.

A dozen years ago, when asked how the company could make money in free keyword search, Larry Page responded that he was really in the business of developing artificial intelligence (AI). The challenge was knowing the difference between what users type as a search, and understanding what they really want.

Perhaps the most stunning product development at last month's Consumer Electronics Show was Toyota's new hydrogen fuel-powered car, breathlessly named the "Mirai" and translated as "The Future."

Toyota was the first to go big on hybrid vehicles over a decade ago, and then lost its mojo to all-electric competition from companies such as Tesla. 

The recent switch to hydrogen is intriguing, because it suggests that the company may be moving in an entirely different direction. 

Hydrogen fuel cells are not new - just expensive.   The hydrogen itself can be sourced from natural gas or electrolysis of water using solar power or conventional sources.   Most fuel cells require the use of platinum in membranes that release electrons from the hydrogen.  Those free electrons are then used to create an electrical current which can power a vehicle's motors.  

There are some huge advantages for transportation, such as complete refueling in 3-5 minutes, a full 300-mile driving range, the performance of an all-electric drive, and much lighter weight than battery-powered vehicles, to name just a few. 

Hydrogen fuel cell cars are extremely clean from an environmental perspective.  When hydrogen combines with oxygen, the result is pure H201.  Yup, that means the sole exhaust is drinkable water.

But things get even weirder from here.  As part of its promotion to sell vehicles in California, Toyota is offering 3-years of free fuel to new buyers.  This will come from any one of forty-eight planned hydrogen filling stations on the West Coast. 

Toyota is rethinking the game in other ways, too.  While most cars are plugged into a garage outlet, the Mirai serves as an off-grid source of power, meaning that you could plug your garage into your car.  Toyota engineers say that a smallish American home could be powered for up to 5-days on a single filling of hydrogen. 

Garry Golden, a New York-based transportation futurist, says that rather than rebuilding a well-established network of gasoline service stations across America, the future of hydrogen-power may resemble the iconic "milkman" model of home delivery, with hydrogen "honeycombs" delivered daily to residences or convenience stories, and the empties picked up and recycled at the end of the day.  

A more immediate scenario involves a gradual build-out of hydrogen-based fueling stations.  The areas to watch, says Golden, are island nations such as England and Japan.

So, has the time finally come for hydrogen-power?  Investors lost piles of money in fuel cell stocks during the early 2000's.  Most have not gotten back to break-even, even though the technology has progressed by more than a decade. 

Key fuel cell stocks that were the "next big thing" such as Ballard Power Systems (ticker:  BLDP) and Plug Power (PLUG) are now "single-digit midgets", trading for $2 per share.  Executives at Plug estimate that the company could break-even by the fourth quarter of 2015, but have not yet reported a profit.  Of the two, Plug appears to be in a better position.

Meanwhile, Toyota (TM) is worth a second look.  This isn't because the company is an innovator in the use of hydrogen power, but because they are good at everything else.  Toyota  is benefitting from a weak yen, and U.S. sales were up 12.7% last December.  Earnings per share are up 23% over the past year, yet the stock is trading at just 12x earnings.   

Will hydrogen live up to the hype?  In this case, it doesn't matter.
