It's a bit long, i am not sure i have the time to watch it. But on the topic of protecting your mind and controlling your emotions i can say this:

• Lose it once, and people will long remember that.

• Put yourself in as many possible situations as possible, or envision yourself in uncomfortable situations, to learn to control your emotions and respond calmly (under pressure too).

• For me, i write it down. Then i re-read it. Then i cut the BS, and hone it to a sharp point, then re-arrange the points to get a compact and clear point.
