You have to treat your dating profile as an advertisement; you are, after all, selling yourself to others.
At the same time, you’re less likely to have success when dealing with dating/hook-up apps like Grindr or Tinder. Speaking of the offline dating mindset: you’re going to have to accept that online dating is even more of a numbers game than dating in IRL or meatspace or whatever the cool kids are calling “the world” these days.
This means sending out more cold e-mails, dealing with more rejections and more dates that go nowhere. It’s part of the price of entry, and it’s better that adjust your expectations accordingly instead of dealing with the slow burn of “WHY WON’T THE MAGICAL BOX PROVIDE ME WITH SEX?
When we meet somebody in person, we have hundreds of thousands of verbal and non-verbal clues to give us an intuitive grasp of who we’re talking to and whether or not we’re into them long before we go up and introduce ourselves.
Everything from how they stand to how they talk, who they talk to, how they act around their friends, how they smell, even the pitch and timbre of their voice indicate whether or not we’re likely to have an initial attraction to them that would prompt us to make that all-important first approach.
We’re able to process all of these signals so rapidly that we’re often unaware of it; to our conscious mind, we’re just eliding over the ones who we read as “nope, not interested” while we narrow our focus on the people who do it for us.
