You need to go out and approach just as many women. Cold approach.
Walk up to them in nightclubs and streets and coffeeshops — make talking to women a part of your life. Online dating has its advantages, but there’s no way matching with that many women beats the hard, punishing trial of building the confidence, outcome independence and self amusement necessary to be authentically yourself with any girl. Suddenly having 150 blind(ish) dates doesn’t force you to improve yourself.
You might think to yourself “I don’t want the kind of girl who’s out in a club,” but for your own good, please reassess that mentality. Learn to be comfortable around feminine energy and remain grounded. That’s the only way you’ll find “the one” and not find that the love is gone a few years down the road when you’re both over the “honeymoon period” endorphin rush.
