Idiom: To start from scratch – To start something from the very beginning
Context #1
Jen: I really admire Keisha. She has become a successful restaurant owner in just three years.

Jen: That’s really impressive! Nowadays, it’s so hard to be successful when starting from scratch. Usually, it’s much easier to just take over a business that is already established.

Jack: Wow! You had to start from scratch after finishing almost half of the book? That’s tough.
Terri: I know. Hopefully, I can do it a little faster this time.
