Many companies go bankrupt every year. The management or owner doesn't understand the need for cash flow, and underestimate the time it takes for the business to grow enough to be self-sufficient. I have done consulting for small businesses, and taught them inventory control. I also consulted a nonprofit in Arizona, because of their poor cash flow. It was an easy solution; the employees needed to cut their salaries based on their revenue flow. I was a Director of Administration for a nonprofit, and made sure that their reserve had a healthy balance. Because their fiscal management was rated excellent, they were awarded more contracts by the state. On a personal note, I was able to retire early and travel the world - having traveled to 128 countries on my last count.
As for the stock market, I have never listened to financial pundits who have recommended that the investor increase their bond holdings as they age. That's balogne. I did the opposite and kept my equity balance at over 80%. My past 12-month return is over 13%. I must admit that the 2008-2009 recession hurt our investments, but made up the loss in 1.5 years.
