the Spearman law of diminishing returns

The Spearman law of diminishing returns suggests that as you put more effort or resources into improving a particular characteristic or skill, the gains you achieve become smaller over time. Initially, small efforts may lead to significant improvements, but beyond a certain point, extra effort yields progressively smaller benefits. This concept helps explain why continually investing in the same area may eventually become less efficient, emphasizing the need to balance efforts across multiple areas for optimal overall progress.
