I think if you put your mind to it, you can achieve ANYTHING.
If you're determined enough, you can write that masterpiece you've always wanted to, you can lose 50 kilos or you can become the President of the United States.
You can take your depression and stuff it down the drain. You can take your past humiliation and throw it to the winds. You can ignore all the naysayers; you can be Superman.
But it doesn't matter if you've got nerves of steel, if you're sleepy, you just CANNOT fight it!
Slap, slap, slap. WAAAAAKE UPPPPPP!
