Surface Pressure

I'm the strong one, I'm not nervous
 I'm as tough as the crust of the Earth is
 I move mountains, I move churches
 And I glow 'cause I know what my worth is
 I don't ask how hard the work is
 Got a rough, indestructible surface
 Diamonds and platinum, I find them, I flatten them
 I take what I'm handed, I break what's demanding, but
 Under the surface
 I feel berserk as a tightrope walker in a three-ring circus
 Under the surface
 Was Hercules ever like, "Yo, I don't wanna fight Cerberus?"
 Under the surface
 I'm pretty sure I'm worthless if I can't be of service
 A flaw or a crack, the straw in the stack
 That breaks the camel's back, what breaks the camel's back?
 It's pressure like a drip, drip, drip that'll never stop, whoa
 Pressure that'll tip, tip, tip until you just go pop, whoa, oh-oh
 Give it to your sister, your sister's older
 Give her all the heavy things we can't shoulder
 Who am I if I can't run with the ball?
 If I fall to
 Pressure like a grip, grip, grip, and it won't let go, whoa
 Pressure like a tick, tick, tick until it's ready to blow, whoa, oh-oh
 Give it to your sister, your sister's stronger
 See if she can hang on a little longer
 Who am I if I can't carry it all?
 If I falter
 Under the surface
 I hide my nerves, and it worsens, I worry something is gonna hurt us
 Under the surface
 The ship doesn't swerve, has it heard how big the iceberg is?
 Under the surface
 I think about my purpose, can I somehow preserve this?
 Line up the dominoes, a light wind blows
 You try to stop it toppling, but on and on it goes
 But wait, If I could shake the crushing weight
 Of expectations, would that free some room up for joy
 Or relaxation, or simple pleasure?
 Instead, we measure this growing pressure
 Keeps growing, keep going, 'cause all we know is
 Pressure like a drip, drip, drip that'll never stop, whoa
 Pressure that'll tip, tip, tip until you just go pop, whoa, oh-oh
 Give it to your sister, it doesn't hurt
 And see if she can handle every family burden
 Watch as she buckles and bends, but never breaks
 No mistakes, just
 Pressure like a grip, grip, grip, and it won't let go, whoa
 Pressure like a tick, tick, tick until it's ready to blow, whoa, oh-oh
 Give it to your sister and never wonder
 If the same pressure would've pulled you under
 Who am I if I don't have what it takes?
 No cracks, no breaks
 No mistakes, no pressure!
