I've had this in my files for a long time and I just came across it today again:

Giving 100%
What Makes 100%? What does it mean to give 100%? Ever wonder about those people who say they are giving 100%? We have all been to those meetings where someone wants you to give 100%. What makes up 100% in life? Here's a little mathematical formula that might help you answer these questions:

If:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z is represented as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26,

Then:
H-A-R-D-W-O-R-K
8+1+18+4+23+15+18+11 = 98%

K-N-O-W-L-E-D-G-E
11+14+15+23+12+5+4+7+5 = 96%

But, A-T-T-I-T-U-D-E
1+20+20+9+20+21+4+5 = 100%

So one can conclude with mathematical certainty that while hard work and Knowledge will get you close, attitude will get you there.
