It is very important to be careful in trading. If we are not careful about money then we will surely lose our money.  Whenever we are more careful about our money we will not take any wrong decision by thinking about the decision several times before taking the wrong decision and then taking that decision. You should always know about new hawk or old hawk trading in terms of trading. There is no fixed limit to knowledge about trading as long as you have been trading. Another important factor in being successful in business is to believe in yourself and not be overly greedy.  Profit and loss is a normal thing in business but business should be done in such a way that the amount of profit is more than the loss but the business is successful.
