Quotes That Keep My Grit-ometer Running 100%

At the age of four, my sister and I got our very first library, "The Young Children's Encyclopedia". It consists of 16 volumes and a diverse array of topics ranging from Sciences to Literature/History/fairy tales and much more. This was my version of today's internet and it marked the beginning of my voracious appetite for abstract reading. Of course, it took us only about 3 years to memorize every chapter, word for word and then we moved on to what other stochastic knowledge the world had to offer. Since then, I've always taken note of quotations that are centered around grit, persistence, tenacity, and resilience. Here are my top 20:
