4) You honed your skills and did not depend on luck.
Successful investors know themselves. They also know the role that behaviour can play in financial decision-making, and they take steps to ward against some of those behavioral traps.
Zoll believes that this psychological or behavioural angle is one of the more interesting elements of investing. He is of the opinion that investors need to ask themselves what has been their experience with money and investing throughout their life and childhood.
For those of you who grew up in a household where saving and investing were encouraged, it may be second nature to you and an obvious thing to do. If you didn't grow up with that as part of your experience, then it may seem like a foreign concept--something you don't know much about. In that case, he suggests that you take some extra steps to educate yourself so that you understand how investing works and make an attempt to to cultivate some good saving habits within yourself.
Zoll also urges investors to think about the kinds of money mistakes you've made in the past; and these don't have to be investing mistakes. Have you fallen for get-rich-quick schemes? Are you subject to impulse buying? Do you often take on more financial risk than you can handle? If the answer is yes to these questions, these may be clues that you really need to watch taking on too much risk as an investor--that you are prone to a certain kind of behavior.
