One day, it will all be worth it.
That story you're working on? Will one day be a book or a film that will inspire many.
That painting you're working on? Will one day be an iconic painting beloved by many.
That thick monstrous textbook you've been bringing around for you to study? Will one day feel lighter like a notebook that once led you to victory, as you get home and take off your lab coat, remove that stetoscope that's been hanging around your neck the entire day, and then you take a glance of that same book in your shelves and you just smile.
One day, it will all be worth it...
How? You give it your all.
