If I've learned one lesson during my career it's never, ever sacrifice quality over quantity. It will get you absolutely nowhere fast---and that's not fun for anyone, especially you. You put your name on your work so it should it always be top notch no matter how long it takes to make it so. Have you ever come across somebody's messy project you had to take over or a highly unsatisfied customer? It's not fun.
So here's to putting your best foot (work) forward.
Have a good one.
