Advice
I heard this more than once and I still use it to this day "If it's not worth doing right, don't do it at all!"
Another one I use ALOT espeacially with the bling crowd nowadays is "Form follows function" when I say this I usually get the DUH look and have to explain it, It might be pretty but if it doesn't do what it is supposed to do, what good is it?
Friday night advice "I might be drunk, but you're UGLY, and in the morning I'll be sober!"
