I totally do not know on how would you control your emotions that is yourself not mine so the only one who can tell you how to control it is you. You just need to have a lot of self discipline and patience because in this business not everyday it is christmas there are some time that you will encounter some bad day loss of money and a lot more but despite of all of it we beed to be strong and think positive to lessen the bad vides and wrong decisions.
