Struggling to fit 10,000 istighfar into my day-any structure tips?

Salam everyone. I’ve been thinking a lot about the power of istighfar. You hear these amazing stories of people doing 10k a day and how it changed their lives. Even smaller amounts are supposed to bring barakah. I really want to give it a shot, but honestly, I have no clue how to reach that number. It feels like a huge mountain to climb. How do I even structure my day to make it happen? Any practical advice would be greatly appreciated. JazakAllah khair.
