When we say trading, it is a mix of educated guessing and luck for what you believe will succeed in the coming years. The profit you get from trading is the fruit of your strong desire to succeed after risking an amount of money that you believe to grow will your trading skills at hand.
yes you are right that trading means that if someone do it in trading than that person will taste the fruit of his hard work and that is trading so than the life of that person will change because he want to change it, thats why a lot of people prefer trading a lot.
