I have lots of hobbies. With Social Security quickly hitting the toilet, one of those hobbies is worrying about my future. I don't want to work forever so I do some investing. Today some of my stock picks didn't do so hot. But in the long haul I think I'll do OK. I'm not a financial wizard or anything, much of what I do is simply buying into what I like or believe in. Here are a couple of my faves and why.

AAPL-Apple electronics. It's really the electronics brand for the growing younger generations. Computers, iPods, phones, what's next? Here in the office and on the street I see more and more Apple product taking marketshare over other brands. My dad will likely never buy a Mac computer, but he's also not likely to buy a new one every couple of years like those in the younger generations.

CMI-Cummins. From what I understand, no one compares to Cummins when it comes to clean heavy-duty diesel engines and fuel economy. With fuel prices on the move, more efficient diesel engines will become a must. Plus newly industrialized countries such as China are building an infrastructure which requires engines and equipment. And once roads are in place, it's likely that a huge fleet of trucks will be rolling down Chinese highways delivering goods.
