Here's what the Beatles have to say about it:

"There's nothing you can do that can't be done.
Nothing you can sing that can't be sung.
Nothing you can say but you can learn how to play the game
It's easy.
There's nothing you can make that can't be made.
No one you can save that can't be saved.
Nothing you can do but you can learn how to be you in time
It's easy.
All you need is love, all you need is love,
All you need is love, love; love is all you need.

There's nothing you can know that isn't known.
Nothing you can see that isn't shown.
Nowhere you can be that isn't where you're meant to be.
It's easy.
All you need is love, all you need is love,
All you need is love, love; love is all you need."

I tend to agree with 'em. How about you? Do you think love is all you need? And is it really "easy"?
