Max, everything is practice. Until one eventually sticks. I thought my marriage was gonna be forever but it didn't turn out that way. I used to have life planned out and think it should be that way or this way. And then it blew up in my face. So now, I don't ever try to judge people or try to fit everything into a nice neat little box. Because I have learned it usually blows up in my face.
You WILL mess up. You WILL look stupid. You WILL do things you never thought you would. But once you realize all that is gonna happen and don't stress over it, it can actually be interesting and makes you a better person. All my mistakes and embarrassing moments have made me less judgmental and humble.
So who cares if it doesn't last forever? Means she really wasn't the one. She was practice. So what if you embarrassed yourself? 1 person in the billions of people on earth thinks you are a dork. I can live with that. Besides, if you handle the situation with grace, less likely they will remember you that way anyway.
