One reason that make me want to travel around the world is because I want to learn new languages and also improve my English speaking skill. I have learnt and practiced my English speaking skill my whole life but I haven't got a chance to speak to a native speaker. So, I think that doing a volunteer might be a great opportunity for me to improve myself.
