This reminds me of one of my favorite quotes I try to live by..
"Tenacity is a most underrated quality in life. We all speak about talent, intelligence, glamour. But tenacity is the common thing for every successful person in life. Maintain that motivation to go from A to B and to keep your focus on that target without any weakening. That is called tenacity; stamina in your motivation."
- Arsene Wenger (Legendary Arsenal FC Coach)
I think the “of course” (involuntarily) assumes that you have to choose a good goal, which, looking at the world, is by no means a given.
Many people show tenacity, persistence, and even obsession, but they choose wrong or mediocre goals, at least if we consider traditional “success” as a "good target".
And I'm not referring to people who spend hours and hours scrolling through social media, showing tenacity, persistence, and unusual resistance to boredom, but to those who spend enormous energy, effort, and time trying to get a minor job promotion that would earn them an extra 10K a year, along with the satisfaction of having given their work arch-nemesis a hard time, instead of using the same energy, effort, and time to earn 100K more a year elsewhere.
I see tenacity and stamina in people who every day look for the best, the most “optimal” diet that will allow them to finally reach the best shape of their lives, instead of using the same stamina to resist a little hunger when they choose and follow the most effective way to lose weight, which is to eat less.
If I look back on my life, one of my biggest regrets is not having chosen better and bigger goals for my efforts: I spent a lot of time and energy trying to make relationships work, instead of using the same time and energy to find someone more compatible with me; I spent energy, time and willpower to get excellent grades in school, without thinking too much about whether those excellent grades would lead me to the professional career I aspired to; I spent years working tirelessly toward the dream of an academic career, before realizing that I did not want to work with students that much, my research was not that groundbreaking, and I wanted to earn much more money than what an academic career could offer.
