Sometimes less is more. First thing is to always be willing to walk away. Your enjoyment and peace of mind is a priority. We aren't looking to have sex with every woman at the expense of our health or sanity. She (or they) have to meet not just your standards in looks, but should meet other standards (behavior, attitude,etc.).
YOU are to screen THEM. To weed them out. You are the one picking and choosing. Not the other way around. You have to be willing to walk away from childish, bratty, mentally unstable, or psychotic women no matter how physically attractive some may be.
The women you choose must not only be attractive to you but they must show a genuine interest in you. This is a primary requirement. Look for interactions where there is mutual interest. Not the one-sided chasing game that so many men play. You must not have the beggar's mentality.
Start paying attention and looking for signs that women are interested in you and meeting them will be very low-pressure and a lot of fun. Instead of approaching women you might have a normal casual conversation with them. Paying attention to whether or not she is showing high interest, then you can leave your number with her. Either leave your number only or leave her your number and get hers in exchange. You have to get a feel for which is better for each situation.
If she seems to be boring or have low interest or a bad attitude you don't offer your number. Quality over quantity. So those are a few things to keep in mind when meeting women.
