Too many times, men approach with the mindset to get her number or to sleep with her. This mindset stiffens creativity and prevents the man from coming up with new ideas.
Imagine if a man approaches another man with the intent to get his number and become best friends. That would simply be creepy.
Instead, the mindset you should take on is to play. That's it. The purpose for you to approach is to play, flirt, enjoy the interaction and togetherness of another person.
Going with this mindset, you may not want her number if she does not qualify. She does not qualify if she does not play along or respond in a positive manner.
As well, because you are just playing, it is okay to smile, don't be so serious and it is okay to say silly things like "Should I get a tattoo?"
So next time, you see a stranger, don't keep your distance because strangers don't like to talk to strangers. Don't worry what the stranger thinks of you. Better to have her think of you than not know you even exist. If she thinks your friendly attitude is wrong, then maybe she is uptight. Everybody starts off as strangers. Uptight people will never get to know anybody.
Every expert tells you, you need to be confident. Oftentimes, this results in an egotistical attitude. A person that lacks confidence hides his fears with egotism. This egotism is not only unattractive to females, it is unattractive to everyone.
However, a confident man need not to act egotistically. He can also claim to be shy and this claim can even come across as an attractive turn on. Claiming to be shy can put her at ease and demonstrate vulnerability and humility which is also an attractive trait.
Just don't really act shy and nervous.
Very often, you will see a mid 20 year old female dating a 40 year old male or a 30 year old female dating a fifty year old male. What do these males have in common?
A 40 year old male should have enough experience that he makes very little mistakes in life in terms of leisure activities, finances and knowing what he wants. This security is attractive to females because she can rely on him to help her reduce mistakes and offer direction and insight she would not know.
So does this mean you need to wait until you are old enough? Of course not, age is not the factor. It is the experience, the knowledge and the success that turns her on. So to gain experience, you simply have to accept more stimulus. Staying at home and watching T.V. won't cut it. Go out, explore, try new things, learn new ideas and discover. The more you know, the more value you can add in an interaction.
