Economies go in cycles. They push to their breaking points, then move in the opposite direction. We saw it clearly in the '90s when there was no end to up (except there was and we abruptly hit it in 2000). In 2008, it felt like there was no end to down. But we now know there is. Things are picking up, and there are numbers to prove it.

Don't be the last to figure out we're in an economic recovery. Sitting on the sidelines, waiting for one more chance to buy a stock at the bargain price you saw in March of 2009 isn't going to happen. Times have changed. The U.S. economy is on the mend.
