Idioms are the colorful aspect of any language. Using them as a non-native speaker, makes your speech less awkward. But remember, never translate them word-for-word (literally) into your native language. Do that and you'll get all topsy-turvy! Now, now, don't panic! Using them is quite delightful if you get the hang of it. It'll be fun and you'll enjoy speaking English much more.
