I'm sure others may have a different definition for you. My definition isn't scientific, just my own experiences after 40+ years. I've found the cycle to be about 10 years per round. out of ten years I find that I will make great profits for about 2 of those 10 years, some losses in spite of everything I may do for about 2 of the ten years, and for about 6 of the ten I make enough to keep my name on the gates. What does this mean? Don't spend it all during those good years. Prepare for the rainy day. What goes up will come down. Right now cattle prices are at record highs. These prices will come down and you want to be able to survive them so you can be there to enjoy those wonderful high prices again.
As I said, this is non-scientific, just my experience.
