1)I’ve
 missed more than 9000 shots in my career I’ve lost almost 300 games. 26
 times, I’ve been trusted to take the game winning shot and missed. I’ve
 failed over and over and over again in my life. And that is why I 
succeed.
  --Michael Jordan
  
 2)Twenty years from now you 
will be more disappointed by the things that you didn't do than by the 
ones you did do. So throw off the bowlines. Sail away from the safe 
harbor. Catch the trade
  winds in your sails. Explore. Dream. Discover.
  -Mark Twain
  
 3)I think and think for months and years. Ninety nine times, the conclusion is false. The hundredth time I am right.
  -Albert Einstein
  
 4)I am here for a purpose and that purpose is to grow into a mountain, 
not to shrink to a grain of sand. Henceforth will I apply all my efforts
 to become the highest mountain of all and I will strain my potential 
until it cries for mercy.
  -Og Mandino
  
 5)Celebrate your 
success and find humor in your failures. Don’t take yourself so 
seriously. Loosen up and everyone around you will loosen up. Have fun 
and always show enthusiasm. When all else fails, put on a costume and 
sing a silly song.
  - Sam Walton (founder of Walmart)
  
 6)Many of life’s failures are people who did not realize how close they were to success when they gave up” 
 – Thomas Edison.
  
 7)Far better it is to dare mighty things, to win glorious triumphs, 
even though checkered by failure, than to take rank with those poor 
spirits who neither enjoy much nor suffer much, because they live in the
 grey twilight that knows not victory nor defeat.
  -Theodore Roosevelt
  
 8)Say what you want to say when you have the feeling and the chance. My
 greatest regrets are the things I did not do, the opportunities missed 
and the things unsaid.
  
 9)So long as there is breath in me, 
that long will I persist. For now I know one of the greatest principles 
of success; If I persist long enough I will win.
  -Og Mandino
  
 10)Never, never, never give up.
  -Winston Churchill ( In his later years, Winston Churchill was asked 
to give the commencement address at Oxford University. Following his 
introduction, he rose, went to the podium, and said the above 5 words. 
Then he took his seat.)
