Stress
Are you afraid of fighting a six-foot-eight, 250-pound man with years and years of training and the promise of a cash bonus if he knocks you out? We hope that even the toughest customer would say "yes." It's risky business, getting in the ring with an opponent. Especially an opponent whose fists are registered as lethal weapons. But hey, it beats working for old man Winters down at the number-punching plant.
While a well-respected prizefighter might fight only four or five times a year and make a great living, most boxers fight at least twice as often. That's still only ten or twelve work days a year, so your job in between fights is to aggressively take it easy so you can recuperate in time to train up for your next bout.
And talk about high highs and low lows. The difference between winning and losing is not only monetary, but important for your reputation. You can't go around losing fights if you want to be the best. Of course, you also have to try not to think about it. That sort of pressure is like a germ-factory of stress that can spread throughout your body if you don't take care of yourself.
It's important to keep a good attitude about your job as a fighter, because avoiding stress in this field is key. Not only is psychological health crucial to focus in a fight, but letting stress get to you can affect your physical health and overall life enjoyment.
No pressure.
If you want to be a pro boxer, you cannot let stress get the best of you. Just remember, any stress you feel is coming from the same energy source you have to harness to win fights.
