Magik said:What's consider "normal" varies from person to person. It just depends where you are at in life and how you view it. You are not wrong in your views in that going up to somebody without any sort of context is a violation to you. Its how you see the world.
For people that do approach women, the woman is the context if that makes any sense.
The problem is majority of men put women on a high pedal stool right from the get go which automatically makes them inferior in their mind. This obviously leads to fear, intimidation, lack of self-worth etc.
When it comes to getting in touch with the "inner cave man" most people simply have lost it due to years of social conditioning. It'll take a lot of effort to revive it, which for a lot of men are afraid of doing because it'll bring up other deep issues.
It also doesn't help that a lot of men are simply clueless when it comes to social interactions with poor body language and simply poor "inner game".
You're also right in that you only have one life, so you might as well make sure you get the most out of it. Nobody wants to be in the their later years wondering "what if I said hello to this girl...?"
This is crucial and what a lot of guys don't get. You can say and do all of the "right" things, but look and sound awkward at the same time. Body language, tone, timing, physical interaction and having a general air of confidence is key. Women sense that shit like a shark smells blood in water. Everything you do should be deliberate. Know what you want to accomplish and do it with little or without hesitation. They're really good at sensing doubt, uncertainty and low self esteem. Fear of being eliminated will present itself in your speech and actions. If you're not careful, your fears will become a self fulfilled prophecy, thus, resulting in rejection.
Basically, if you pay attention to what you're doing and speak and act with conviction, on the most part, you should be alright.
