INVESTING SIX PEOPLE WHO HELPED SHAPE A TUMULTUOUS DECADE

Failure to cut losses: Pride, ego, or stubbornness prevents the trader from selling. 
Not knowing “how much” to trade on each position: Overtrading positions can kill your account and take you out for good (risk of ruin). (Learn to position size) 

Average down in price: Placing good money after bad is a loser’s game. 
Listening to rumors: Forget the talking heads, rumors and tips as they are nothing but garbage and a sure way to substantial losses 

Lack of patience: It takes years to master trading as an advanced skill; even then, you are never done learning or adapting 
Not knowing when to sell: Determine your price objectives and risk-to-reward ratios prior to entering the trade; never allow emotions to make this decision.
 
Pure Fundamentalist: Technical analysis is a must! Use candlestick charts that show the price, volume and major moving averages – this is all you need, don’t complicate the process.

Lack of action: Be able to move on a dime. Time is money, don’t procrastinate or hope for something that may never happen. 

Lack of Consistency: Develop a method suited to your personality; stick to it and don’t trade blindly.
