When my sister says it to me I know it's not all good and nowhere near good.
I know the feeling, have a friend just like that 😂
I encourage people to make small changes, start with the smallest thing and then the next and so on
Yes, I've found this to be really effective for me. There is a book called "2 Second Lean" that talks all about this. The company requires every employee to make one improvement every day that saves 2 seconds or more. It's super fascinating if you look up FastCap or Paul Akers on YouTube they have a bunch of videos showing improvements.
Anyway, I try to do this for myself at work and home. I don't do it every day, but I have made so many small improvements that compound to make a huge improvement in my life and work.
