Youg girls, specially ones that feel have been burned by guys,will be very impressed when they run into a guy who takes no crap,and has his game together.
Just remember, most young guys don't know what's up when it come to women. The ones that finally get it, it took them a while to figure out. This is why we often say "I wish I knew what I know now when I was 18."
Most older guys don't know what time it is either. Imagine, a younger guy, her age, with very little game, competing against you in your 30's, who has his act together, and knows how to deal with all types of women, and is ready to walk away from any girl regardless of how hot she is.
Being in your mid 30's, you have to realize that your perceived value will be higher with girls in their mid-late 20's than it will be with the teen age puss. At 18-22 age range, they are attracted to guys for all the wrong reasons. By the time they are in their mid 20's, they know what's out there and can be more impressed with somebody older. This might be the same girl who at 19 "would never date somebody over 24." LoL.
As long as you come across as always doing something,and being busy, they will look up to you. And of course, as long as they're is an initial attraction, you will be able to amplify it by acting like a man who goes out there and takes it.
As long as you are able to turn all YOUR ADVANTAGES of being older (financially stable, mature, experienced, busy, etc.) and turn them in to benefits she can't overlook, you'll do just fine. So use your advantages to the fullest. If you don't have any, or don't see em, then its time to get to work. Your attitude will, and "Inner Game" will determine how successful you are.
My favorite technique to use on a much younger girl (8+ years), after some attraction has been established, I start calling her a "child." Kinda like a neg hit. If she's interested it will create doubts in her mind, as all of a sudden you want "mature" women, and she know must prove herself. You are now the choser.
If I had to pick ONE single program to learn from, if you already haven't, it would be David DeAngelo's Double Your Dating. Read his e-book, then get the DVD Advanced Series. Guys in their late 20's+ are probably more bold and likely to pull some of the "Outer Game" covered. I say this because most of his guest speakers are in that age range.
