Ted (2030) : "Kids, you can ask the universe for signs all you want. But ultimately, we only see what we want to see when we're ready to see it."

Ted : "Look, think about all of us five years ago, when we first met you. Marshall and Lily were just boyfriend and girlfriend, now they're married and thinking about kids. And Barney, Barney was never going to commit to anyone, ever ! And last year, he fell in love. And me ? I was chasing some girl I was convinced was the one. Now she's one of my closest friends. And you ! Five years ago you never would have chosen love over your career, but today, you did."
Robin : "Looks like I'm getting dumber."
Ted : "No, just more courageous. Look, we've all been searching for the five doppelgangers, right ? But eventually over time, we all become our own doppelgangers. You know, these completely different people who just happen to look like us. ‘Five years ago Robin’, that girl, she was pretty great. But ‘Doppelganger Robin’ ? She's amazing."
