In the past, I would see "hard work" as a form of sacrifice, working hard, putting effort into certain things.

Later, I realized I was somewhat living in my own illusion, having overly high expectations for many things.
Now, my mindset has shifted — I am indifferent to effort, treating it as a matter of course.
Don't get emotionally moved or glorify your own contributions.
Once your mindset changes, you'll be able to keep doing it day after day.
