I have been trading stock and forex for more than 9 years now and of a truth it takes fearless mind to do so. You want to succeed in trade then you need to remove fear out of the way. Fear make you to lose money and opportunity.
You are right. for you to make it big, you have to be a risk taker. However, it is easier said than done and when you take blind risk, i can assure you that no big reward awaits you. It is not just about taking risk, if you dont take calculated risk you will get Rekk and when you do, you won't certainly have the opportunity to try again another time
