What is the result of persistence?

Can you elaborate on the potential outcomes of persistence? Is it a guaranteed success, or are there varying degrees of success that one might encounter? Additionally, how does one measure the success of their persistence, and what factors might influence the end result? Is it solely dependent on individual effort, or are there external factors at play as well? I'm curious to understand the intricacies of this question and how it applies to various aspects of life, including cryptocurrency and finance.
