Money Vs Performance

"You don't get a raise on the promise of better performance; you get a raise only by demonstrating better performance. You can't harvest money unless you plant the seeds that grow money. And the seed of money is service. Put service first, and money take care of itself." -David J. Schwartz

To ask for a raise, before demonstrating better performance, is like wanting an apple from a tree we haven't yet planted. Find ways to hone your skills and do more prior to ask for a raise and you'll be more likely to get one.
