By itself, being short should not drastically affect your ability to get laid unless you are like a sub 5'4. I see short guys (under 5'8) who are with decent looking women often.
Now, if you are 5'3, never work out, and look like you are barely put together, yes, a picture is worth 1000 words and most women will instantly have a wall up. They are programmed to want strong men. I don't know anything about you personally, MDJ, but I am guessing that your lack of success is probably more of a confidence issue than it is due to your height. That said, I have little respect for the "Black Pill" as an ideology -- it is completely defeatist and offers little in the way of constructive life change for men.
