The convenience (ease and comfort) of online dating and the apprehensiveness of cold approaching differ greatly in the initial 'approach.' It is the mental process during the approach that develops inner confidence.
Approach Anxiety
The mental fluctuations to get in your head whether or not to start a conversation. You mind is telling you to man the fυck up, but your feet feel paralyzed. Or your mind is telling you that she just wants to get her coffee and go, but your are moving towards the target in place. That's the power of the mind, unless you train to think differently, it will always stay in its comfort zone. Because...
Fear of Rejection
For most people, this is the greatest motivation killer. Rejection can be so intense for people that society has taught us to skirt around it. Point out their positives before denying them what they want. The last meal before execution. You get over the fear of rejection by having it dished out to your face over and over again. It's going to leave a bruise the first few times, even first hundred times. But soon, it will start hurting less until you are almost immune to it. Because...
Regret
Today, there was a girl waiting for her coffee at Starbucks. I was on the phone and exchanged eye contact and a smile with her. She grabbed her drink, turned around smiling at me and left. What if I just yelled out WAIT! Coulda, woulda, shoulda, it was a fleeting moment and I'll never see her again.
With social communications today, we experience a lot of rejection indirectly. It's there to ease and comfort us, it's a convenience to our feelings. Nothing hits closer to home than a stone cold No to the face, but you must experience it over and over again to achieve genuine inner confidence. You can absorb the blοw with a grin, or you can conveniently click onto the next profile.
