Try

Pink's song "Try" has gotten me through a good many tough runs.

I heard it first on "The Biggest Loser" and then went searching on You Tube!

Chorus:

Where there is desire there is gonna be a flame,

where's there is a flame someone's bound to get burned.

But just because it burns doesn't mean you're gonna die.

You gotta get up and try, try, try!

Here's the deal:  Desire is what makes me go out and sweat, run longer
 than I thought I could and lift more weight than before.
Desire is what ignites the flame to push.  

Yes, it's exhausting and it burns "but just because it burns doesn't mean you're gonna die."

When I'm out of steam and I don't think I can go any further I remember this:

Remember your desire and why you started in the first place.

You can go further, faster and lift more.  

TRY!
