About seven years ago, shortly after my wife and I moved into our house, it started raining, and the roof began leaking. We hadn't been in the house a year, and so naturally we wondered if the previous owners of our home knew anything about this. But I hardly had time to dwell on the dampness of our new dwelling. About two months after filing a claim to have some roofers make some repairs, a lightning strike took out our sump pump in the basement in the middle of the night, and when I came downstairs in the morning, I was stepping onto a wet, mushy carpet underneath about two inches of water.

Before the water even receded, we filed another claim, foolishly thinking that that's what a home owner should do. What can I say? We were young and stupid. Almost needless to say, we were told that our policy wouldn't replace the soon-to-be-molding carpet and received a check for a few hundred dollars to replace my damaged fax machine and other random items in my home office. Then, as anyone experienced in this sort of thing can predict -- our insurance dropped us. Our crime? Filing too many claims. Two in about six months, in fact. I still sometimes lie awake at night, feverish and guilt-ridden for having the temerity to use my home owner's insurance.

Insurance is a necessity of modern life. Face it, there is, as yet, no way to guarantee that nothing bad will ever happen to you or that you will live forever. Oftentimes, though, people forget that simple fact and discover all too late that they did not adequately protect themselves.

The good news is that getting proper insurance coverage does not have to be expensive. Even the most pricey insurance is a pittance compared with the costs that could be incurred if you lack sufficient protection. Below are 10 types of policies that are worth the money:

Life insurance
This is especially important if people count on your salary to pay the bills, whether it's your spouse or your kids. "Many people put off getting life insurance," said Jeanne Heisler, a New Jersey agent. "It's very inexpensive, especially if you are young." Single people may not need the coverage if they have enough money to cover their funeral expenses and pay off their debts.

Homeowner's insurance
Banks require that people get this coverage before they agree to underwrite a mortgage, since it protects homeowners from damages caused on their property to other people. The key for homeowner's insurance is to make sure that there is enough to cover the replacement value of the home, according to the Insurance Information Institute. Personal items such as furniture, sports equipment or clothes are also protected under these policies from "insured disasters" such as a fire or hurricane.
