GLEE! Such an adorable show. But, we're not here to talk adorability. First a little background: Will & Emma are both teachers and while crushing on each other, there are of course obstacles keeping them apart.
Ok, back to lesson... something happens and Emma decides to finally just lay it on the line and tell Will that she would do anything to be with him. Commercial/interaction with kids/singing...and then Will realizes his life would suck with out her. (Kelly Clarkson blaring in background- click GLEE to see how it ends.)
So here is the life lesson: Just Say It! Especially when it comes to love. There is nothing more tragic in life than not going for the love that you want. Even if it is unrequited (which I get totally sucks, believe me I've been there) at least you said it.
There are no guarantees in life, but if we don't at least go for it we'll never find our JOY!
(...and in your search for love, may I suggest you check out The Dating Optimist she gives excellent advise ☺)
