What Do 'they' mean

I've heard of "Practice Makes Perfect"
I've heard of "Nothing Is Perfect"
I've heard of "Impossible is Nothing"


Tell me then, will they get long with each other if they were to be formed in one 1 sentence?? I doubt so.... the can, if u do some little tricks on them, transforming them from PowerPufffs gurls to PowerPuffs boys

Check tis out :'Practice makes Perfect, Perfect is Nothing, Nothing is Impossible'

Now tell me is Practice= Impossible
Impossible=Perfect
Perfect=Practice
