Train like an animal because if you don't you are just wasting your time.
You are the Lion of the gym. Act like it. The Sheep and Cows can sit on a machine and watch TV but you're there for a purpose.
You're there to strengthen your body and mind. The only way to do that is to push yourself past any limits you think might exist.
The other weaklings in the gym have accepted limits.
That's why they look the way they do. That's why they act the way they do. That's why they are frightened.
But not you. Not anymore. Not ever again. Lift that monster weight. And do it again and again.
That weight doesn't want to be lifted. That weight thinks you can't lift it. That weight is mocking you.
What that weight doesn't know is that you do not accept limits. You will lift that weight. And if you fail you WILL try again and again until you succeed.
So do it. Go all out. Leave everything in the gym. If you leave the gym and you still have more in the tank you have failed. Leave everything in the gym.
Take it to the limit. Past the point of no return.
If you aren't willing to sweat for it you don't deserve it. If you're willing to die for it it's yours for the taking.
