Success is not something that you run into by accident. It takes a lot of preparation and character. Everyone likes to win but how many are willing to put in the effort and time to prepare to win? It takes sacrifice and self-discipline. There is no substitute for hard work. 

Henry Ford said, "The harder you work, the luckier you get."

The world is full of willing workers, some willing to work and the others willing to let them.

I like to work half a day. I don't care if it is the first 12 hours or the second 12 hours.

--Kammons Wilson, CEO of Holiday Inn

One cannot develop a capacity to do anything without hard work, just as a person cannot learn how to spell by sitting on a dictionary. Professionals make things look easy because they have mastered the fundamentals of whatever they do.

If people knew how hard I had to work to gain my mastery, it wouldn't seem wonderful at all. --Michael Angelo

The average person puts only 25% of his energy and ability into his work. The world takes off its hat to those who put in more than 50% of their capacity, and stands on its head for those few and far between souls who devote 100%. --Andrew Carnegie

Excellence is not luck; it is the result of a lot of hard work and practice. Hard work and practice make a person better at whatever he is doing.
