Are you one of those people that are always working? Do you spend countless hours studying, designing till early morning, working late at your job, or training till your muscles ache? Well there is nothing wrong with working hard and always being busy (as long as you take some time for yourself once in a while). My grandfather would regularly recite part of Henry W. Longfellow's poem "Success" to me:

"The heights by great men reached and kept
Were not attained by sudden flight,
But they, while their companions slept,
Were toiling upward in the night."

So keep working hard, stay focused on your goals, and you will achieve much success.
