I usually praise them with a little bit exaggeration on their original habits or practices. However, I found that people usually don't accept advices if they are not ready to change. Maybe only me...?

Hi, Ms. Anna!  understand where you're coming from regarding giving praise and advice. It's true that people sometimes resist advice, especially if they're not yet open to change. It's not just you—many of us have experienced this. It can be challenging when we want to encourage someone but feel like our efforts aren't always welcomed.
