Choosing hard is important. Hard defines you...much more than easy. No one remembers you for going through the motions...writing a work schedule, sending a store bought birthday card or mowing the lawn (unless you're in a wheelchair). Hard shows the rest of us that you care enough to do something meaningful and follow-through. Even if you fail, the act of trying matters. It shows the world you make tough choices, are willing to put some skin in the game and that you'll slug it out to be better than average.
The key then is to define hard in your category...to be the one everyone else points to as the measuring stick. Whether you own a restaurant or are a freshman in college, defining the standard of hard has the same effect...you get noticed.
Some to get you going...
