As with Asset, Liability has several meanings in actual use. Bankers typically just consider debts to be liabilities. Robert Kiyosaki, in his book Rich Dad, Poor Dad, states that a liability is anything that continually drains money from your accounts, or as he states it "Assets feed you, Liabilities eat you."
Now that we've talked about both assets and liabilities, let's look at some Kiyosakian views in our personal lives. Homes would be liabilities, as there is not only a mortgage, insurance and property tax but also maintenance. A stock with a dividend would be an asset, as it is paying you on a regular basis. Royalties would be in the same classification. You do the work up front, and receive income for a period of time after that.
If you change your financial view of your world to these definitions of Assets and Liabilities, it gives you a more realistic view of where you stand. If you then focus on acquiring assets and divesting liabilities, you will better be able to weather life's storms as they come.
