Work and love
If most people tried to find a life partner the way they look for a job, most people would never find one.
The reason is simple: You can’t decide if you like someone based on your impression of a one-page document. Let alone a twenty-minute intro call.
Moreover, most people wouldn’t choose to date their mate without the added context of their relationship. With nothing left to go on other than a (short) blind date, I’m almost certain very few partners would end up together.
No, the way you learn to like your best half enough to date them, move in together, and spend your lives together is gradual. And that begins with putting yourself on their radar in a way that encourages them to give you a chance.
You can’t create a relationship without one and the other. You, putting yourself out there (risking rejection), and them, giving you the benefit of the doubt…finding your awkwardness more of a charming quirk than an enduring character flaw.
Whatever the case, sending out handwritten (love) letters in droves, praying someone will call you back likely isn't the best approach.
