Sorry you have these regrets, we all have things we would if we could, do over.
Statistically I work in one of the most dangerous occupations there is farming, I work long hours with dangerous machine and large animals, my WCB rate is one of the highest there is for an operation that has never made a claim. I do it because I love it and I am a risk taker. The risk taker is most evident in the chosen recreational activities of my youth mountain climbing, alpine skiing, free diving, white water canoeing, wilderness exploration and scuba.
I can't imagine taking the risks I have or do for money.
My father was a bookkeeper in a foundry who pour brass in his spare time, then he was a soldier in the war and then he, too farmed. My grandfather was a teacher, principal and then a farmer and his father was a farmer. I have gone back many generation and on my father's side it's all farmers and soldiers.
