Did you ever think you have not failed enough? Sounds crazy, right? Yet many of history’s greatest achievers succeeded only after a multitude of failures. Abraham Lincoln failed in business and politics before he became president. Thomas Edison dropped out of school and failed thousands of times before inventing the light bulb.

If you had a bad week or faced disappointment, remember that failure is a learning tool. Making mistakes and learning from them can provide the tools for greater success.

"I want to find people who have had to work hard and who have learned from their failures. Perseverance is no guarantee you'll succeed, but without it, it's almost guaranteed you won't" - Steve Case, former founder and CEO of AOL
