"Remember as an Investor, Rome was not built in a Day. Remember as a Trader, Hiroshima-Nagasaki was destroyed in a Day." Explanation : One statement is about Construction and Second about Destruction, Both shows very important attribute for successful investor and trader. An Investor should always have Patience and know power of holding, as they should understand that Rome was not built in a day , hence their investment wont grow exponentially in a short period. A Trader should always follow risk management and risk less, He should understand power of compounding, power of adding small profits, if he tries to make it all from one trade, He might see result of Hiroshima - Nagasaki. From My Dictionary, this is a good interpretation of this statement, Thank you for reading.
