I like to buy a company any fool can manage because eventually one will.
Investing is fun and exciting, but dangerous if you don't do any work.
When you sell in desperation, you always sell cheap.
You should not buy a stock because it's cheap but because you know a lot about it.
If you can find a company that can get away with raising prices year after year without losing customers (an addictive product such as cigarettes fills the bill), you've got a terrific investment.
Imagine if you borrowed your parents' car without permission and ran it into a tree, how much better you'd feel if you were incorporated.
