"Many men fail because they quit too soon. They lose faith when the signs are against them. They do not have the courage to hold on, to keep fighting in spite of that which seems insurmountable. If more of us would strike out and attempt the impossible, we very soon would find the truth of that old saying that nothing is impossible... abolish fear and you can accomplish anything you wish."
"From time to time, life as a leader can look hopeless. To help you, consider a man who lived through this: Failed in business at age 31. Defeated for the legislature at 32. Again failed in business at 34. Sweetheart died at 35. Had a nervous breakdown at 36. Defeated in election at 38. Defeated for Congress at 43. Defeated for Congress at 46. Defeated for Congress at 48. Defeated for Senate at 55. Defeated for Vice President at 56. Defeated for Senate at 58. Elected President at age 60. This man was Abraham Lincoln."
