Talking to others with Dutch courage by the help of whisky ? Sounds comical. Being afraid of making mistakes while talking to someone in a foreign language is something that I can't handle with too. Grammer rules work all the time but Im sure that noone will laugh at you when you make a mistake, at the end of the day it's not your mother tongue. All in all we just need to be brave.

easy way - drinking a lot of wisky))) 

yes its true for learning any language first we have to speak. In begining we can be poor but, we must speak it with our self loud. it will improve our english.
