It is true, however, that at 13-14yo, one has a lot of maturing still to do. That's true regardless of LOG. So even if you found "the one" person in the world who was actually compatible with you at that age, there is no guarantee that the two of you would be compatible at age 25, when you're both nominally "done growing up."
I'm not sure what "compatible" even means, to tell you the truth.
And people change all the time.
I certainly don't want to be like I am right now in five years. I would prefer to have some maturity and some idea of what I want to go do with myself.
