Someone once told me that never underestimate anyone who doesn't lose temper.
This kind of people usually possess great capacity.
They can be really resourceful friends.
And they can be really fierce enemies.
Humans are emotional animals.
It's our nature to have temper.
And it's totally natural to lose it when something or somebody irritates us.
But there are people who don't.
And that's a fearsome skill.
The more incompetent a person is, the easier he is to get angry.
The stronger a person is, the less you see him throw away his calmness.
Can you hold your temper?
If you want to achieve great things. Practice to do so.
