hey and welcome to as you put it 'the game'
I'm glad to hear you're in it to improve yourself and not to take advantage of women.
allow me to try and answer some of your questions, some you have to answer and choose yourself. Social skills are like anything else in the world, you have to work on them and if you don't you'll just end up being 'wiped out'.

And it is true my friend, i can say i have been in your shoes 'is this right, is it really this easy?' well the simple is 'yes' it is right as long as your intentions are right. Don't loose you're morals just loose the wimpish boy inside.
as about the language barrier, you'll soon learn to use that to your advantage, take me the other night. PUA all boils down to being a more positive, fun and centered.
If your happy with your situation, then PUA is not for you it's all or nothing, trust me knowing a bit is so fu.king annoying and you will be worse off than before.
so before you start, be ready to take what the world throws at you, take nothing personally, be able to laugh at your stupid mistakes, you can't beet going for a kiss opened mouthed

i won't forget the surprise on both of our faces.
If you need any help feel free to PM, but most of all get out their, if at first you have to drink to get the conferdent than do but slowely make it less you make so many mistakes whiles drunk
all the best bro
