You will never get the one you really want.
Okay kids, let me tell you about love.
You'll never get the person you want, not for a moment, they will always go for someone better looking, or with more money.
You will however delude yourself into thinking that some other person down the road is the one, even though you will never love them like you love the ones you want.
You will deny that you feel anything but love for these people, because the idea that you're going to spend 9/10 of the rest of your lives with someone you feel nothing but contempt for is going to make you feel like h***.
Get ready for it, life gets less fun as it goes on.
