I keep wondering, if you lose one does it really mean you'll find another?

Yes, No, Probably

For an optimist, yes.
For a pessimist, no.
For a realist, probably.

Probably.

[The past is what you think of it, the present is what you'll make of it and the future will be the result of it all. And as it seems, the present counts much more than anything else now doesn't it? It really is, afterall, the only thing you can control.]
