Native speakers are always happy when they see foreigners learning their languages, and they came here to help you and you help them ^^ We all make mistake, i'm sure that they make mistakes while speaking Korean too so don't worry about it, and enjoy learning, girl "I can accept failure, everyone fails at something. But I can't accept not trying." Michael Jordan so give it a try and good luck :))

Firstly, you need a good knowledge of vocabulary and grammar: it's easier to feel confident when you know the right words and structures! Secondly, you need listening and speaking practice, being able to understand what other people say will increase your confidence! Since you work with tourists, I suggest practicing specific vocabulary, idioms and sentence connectors. You will sound professional, well prepared and confident!
