It means exactly that, put yourself out there. Talk with as many girls as you possibly can. Open your eyes and look for opportunities, they are EVERYWHERE. Use dating sites. You have to think of it as you're jobless and looking for a job, apply, apply, apply.
Essentially it means making more of an effort and being confident you know going to bars or were-ever girls go to hang out were you live, and talking with them trying to get numbers, putting yourself out there.
