I've made so many mistakes I lost count a long time ago.
Make a mistake, correct it as best you can, move on to the next mistake. Life is a series of mistakes. The best role model for this is Tom Brady--yes, the quarterback. Had no business winning his last three Super Bowls, made mistake after mistake. But did he dwell on them? No, if he had those games would have been lost. Like in the movie Vanilla Sky, "Every day is another chance to turn it all around."
Dwell on your mistakes and you're doomed to repeat them. Move on and you get another chance to NOT repeat them. To get it right.
Having said that, my LAST big mistake was, um, let's see...

Married a troubled young woman figuring I would solve her problems and improve her life. While I think I accomplished that, it also created so much turbulence in my own life and eventually a divorce...

The working one is quitting my current job for a job that was closer to home. One closer to home didn't work out and had go back my job now. For personal mistakes it's a tie between voting for one our jail bird govenors / being religious for most of my life. I'm so glad I'm free from the bs.

I worked one season as a cashier at the aquarium. Although I am a working accountant, I could NEVER balance at the end of the day. The digital register confused me.
That's all. I can't recall any monumental errors...

Personal life married my ex

got married.

I made a bad decision - the cost - friends died and I lost my sanity.

One of my employees made an accounting error that embarrassed an attorney in front of his client. It was very minor. The attorney would not let it go and kept berating the poor guy. I finally had it and sent him an email apologizing and asking him what else we could do to make this go away...I offered to wash his car, babysit his kids, etc. in a joking way...I thought I sent it to him, but apparently, I sent it to the entire firm...needless to say, the attorney was mortified that I made him look like the petty little shithead he was...I got banned from email for a week...

I now send emails to myself first...and often delete them...I can be hot tempered...

"Cancercize" new YMCA flyers said instead of "Dancercize." Fresh from the printer. As the program director, I was responsible. (slaps forehead)

Laughing, secretaries and I jokingly planned a class to give people cancer:

1. Arrive and immediately lie down on a mat.

2. Smoke 10 cigarettes.

3. Eat a cheeseburger and French fries, followed by 10 strips of bacon.

4. Fall asleep.

We fixed the Dancersize flyers.

That’s the biggest mistake you’ve ever made?!!!!!
You my friend are a true saint.
Your biggest mistake was being nice

My list is far to long and embarrassing to list.

It shows your warm heart and innocence...give people enough food so they are not hungry...lovely story...not a mistake but a life lesson that stuck...help as many as you can...awwww
