I quit a high stress management job, ultimately getting into tree work, because my BP was 180/140. I was so stressed I was ready to stroke. Talk about hotheaded.
For me two things brought my BP back down and my stress under control.
1) Hard exercise almost every day. As my body got stronger, so did my head.
2) This one is the key... everything you encounter at work... and I mean EVERYTHING... is little [bad word]. <this when censors ruin a sound statement> A loved one who's sick or in trouble -- big [bad word]... everything else -- little [bad word]. Lose $1000 on a job? Little [bad word]. Guy quits and leaves you in a lurch? Little [bad word]. You get the idea. If it can be fixed or gotten past, it's little [bad word].
Letting little [bad word] get to you is weakness. Are you weak? No, you're a climber. Don't let the little [bad word] get to you. You can control it but you have to do it actively, it doesn't just happen.
Are you a crew leader? If you're a leader and you let [bad word] get to you, you're undermining your own authority. It's easy to blow off someone who gets hot under the collar and peole will do just that. The minute you get hot and show it... you lose.
I'm not saying don't get angry, that's normal. I'm saying get a grip on it; control it so that it doesn't control you.
Yes quitting smoking will cause you to get short tempered but it's temporary. Don't give up because you'll have to do the whole pissy hothead thing again next time you try to quit. Gut it out, stay clean and live better for it.
Just what makes a word bad anyway?
