Do you have a dog? If not, get one, or borrow one from a friend. Offer to take the critter for a walk around town or in the park! Mature women love to see a young guy walking his pet and she might strike up a conversation with you-especially if she has a dog of her own. If it happens to be a younger woman who tries to come on to you, be polite but move on.
When you approach in a confident, easy-going way, most women drop their guard and open up to the conversation. However, if you approach in a nervous or appear intimidated by the women, they will automatically close off to you and the conversation. Why? Women are attracted to the strength in men and turned off by the weakness. This is why confidence is the #1 thing you need to have before you begin trying to meet new women.
