1. Why is it his choice to play disc golf for a living, but not his choice decide to punch his mini? Why does he have to decide between meeting your standards for composure and doing plastics engineering?
You make a good point he does have the choice to punch his mini and he exercised that choice and as a consequence he injured himself and will not be collecting any prize money from the event. He does not have to meet my standards. He can and has chosen to show himself to the world for what he is. And my take on his choice is that he's an immature arse. You may not agree but that is my conclusion based on what he's shown me.
2. Now that shit has hit the fan for you, why is it your choice to choose another employer or career, but not your choice to express anger or frustration with the situation? What could you "sign up for" that didn't have good and bad? Doesn't it seem kind of absurd to make an ultimatum between never expressing anger or frustration, and finding a whole new job or career?
Yes, I do have the option of having a childish temper tantrum. I have chosen against that option as I have decided a long time ago it is foolish, unproductive and unnecessary. There is good and bad in all professions. I could "sign up" for employment for another company, another position in my current company or another career altogether if I felt the change would have a more favorable good to bad ratio than my current situation. This is a decision I mull over nearly everyday but for now I've chosen to accept bad circumstances that come my way as I also accept the good circumstances also.
Like it's been said above, I'm not advocating in favor of mini-punching, at least metal ones, and it's super great that you've been in complete control of your temper since you were ten years old. But not everyone's you, ya know, and not everyone's as good at holding their shit together 100% of the time. Maybe you could cut folks some slack?
