What we can achieve is up to us. The world’s movers and shakers encourage us to pursue excellence no matter what we do— to keep learning, keep working, keep moving forward with due diligence and a sound mind for the sake of a greater world.

Here are some quotes to inspire you to keep doing your best:

“If a man is called a streetsweeper, he should sweep streets even as Michelangelo painted, or Beethoven composed music, or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and Earth will pause to say, ‘Here lived a great street sweeper who did his job well.’”  –Martin Luther King Jr.

“Gardens are not made by singing, ‘Oh, how beautiful!’ and sitting in the shade.” –Rudyard Kipling

“What we hope ever to do with ease, we must first learn to do with diligence.” –Samuel Johnson

“A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.” –Winston Churchill

“Quality is much better than quantity. One home run is much better than two doubles.” –Steve Jobs

“Nobody who ever gave his best regretted it.” –George Halas

“The way to get started is to quit talking and start doing.” –Walt Disney

“A person who never made a mistake never tried anything new.” –Albert Einstein

“Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.” –Aristotle

“Remember to celebrate milestones as you prepare for the road ahead.” –Nelson Mandela

“Opportunity is missed by most people because it is dressed in overalls and looks like work.” –Thomas Edison

“Learning never exhausts the mind.” –Leonardo da Vinci

“If people knew how hard I had to work to gain my mastery, it would not seem so wonderful at all.” –Michelangelo Buonarroti

“Determine never to be idle. No person will have occasion to complain of the want of time, who never loses any. It is wonderful how much may be done, if we are always doing.” –Thomas Jefferson
