You shouldn't have a problem establishing the kind of security you'll both need in a friendship, because you are probably very close in age and have similar values. You'll both want things to be the same way -- and you'll have the same idea about how to make it happen. The structures of your lives will blend together really well, because you'll have such similar ideas -- what social or public roles you'll want to take on, and so on.
Of course, this aspect does have some pitfalls related to the maturity level of the two of you as individuals and of your friendship itself. A mature relationship between two emotionally developed adults will only be helped by this influence, as it will further stabilize you. You already know what you want out of life, and this relationship will help you move toward it.
