Firstly, never worry about asking for advice here. At least 3% of the responses you'll get will be half decent. Maybe 4% on a good day

Also, I see you work as a barman? What kind of bar is it? If it's the kind that gets the sort of girls in that you're interested in, you're laughing. I worked in bars when I was at uni too and once I knew what I was doing found it a goldmine of picking up women... but that'll come later - one step at a time.
