With engineering, I view this year's failure as next year's opportunity to try it again. Failures are not something to be avoided. You want to have them happen as quickly as you can so you can make progress rapidly. Gordon Moore
Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb. Winston Churchill
You don't make progress by standing on the sidelines, whimpering and complaining. You make progress by implementing ideas. Shirley Chisholm
If you're walking down the right path and you're willing to keep walking, eventually you'll make progress. Barack Obama
Praise the young and they will make progress. Irish Proverb
Tortoises only make progress when they stick there necks out. African Proverb
