Anyone can do something when they want to do it. Really successful people do things when they don't want to do it.
Dr. Phil McGraw
Lazy people have a knack for getting done all the things that are not true priorities. But when it comes to the hard stuff, they find every reason why they could not complete the task. That's because hard stuff is, well, "hard."
Those who are successful at what they do know this. And instead of shying away from the challenge, they make themselves do these "hard tasks" first.
