I've met a few people in my time who were enthusiastic about hard work. And it was just my luck that all of them happened to be men I was working for at the time.

A good idea is about ten percent and implementation and hard work, and luck is 90 percent.

I'm lucky. Hard work is the key, but luck plays a part.

Nothing can substitute for just plain hard work. I had to put in the time to get back. And it was a grind. It meant training and sweating every day. But I was completely committed to working out to prove to myself that I still could do it.

It's more parts than people. Their hard work is commendable. They've been great under such a strict deadline.

People who've had a stroke often lose arm function, and it can take a lot of hard work to get it back. The robotic arm allows patients to perform guided and assisted movements over and over again--up to 1,000 repetitions an hour--to improve range of motion, strength and ultimately function in the arm.
