Best practice means doing something in the best way possible, using skills, knowledge, experience, and research to make sure that what we do is the most effective, efficient and safe way to get things done. Think of it like using your best efforts to do a job well, like when you color inside the lines, write neatly, or use your manners at the dinner table. Just like how you have learned the best way to do things in your own life, grown-ups follow best practices to make sure they do their jobs right and achieve their goals. It's like having a set of rules to follow that helps us make good choices and ensures we get the best possible results.
