This is what I did.

I started doing zul farrak, and again, and I did it a third time, by this time I was like,

"oh screw this! I'm quitting!"

So I went to the bathroom. I looked into my eyes, and started to peptalk myself.

"You want this? You want 70? You better grind you laze m*****f****! Go on! Get in that instance! Show em what you got! HUZZAH!"

Then I went back into zf, one run, two runs, three runs. Yikes, this is so damn boring!

Back to the mirror. "Damn you lazy ass slacker! You want to fail that badly you sick masochistic biatch! Zul farrak is waiting! Pull yourself together, act like a REAL MAN!"

Back to zf, one run, two run.

Eventually the mirror trick didn't work anymore as well, so I started ordering myelf around.

"Come on you rotten piece of shit! DROP AND GIVE ME 50!"

Etc, etc.

Eventually I reached 70. And I got the muscles to show for it.
