The road to success / failure

- "We learn from our failures". Charles Jettering, the engineer who among his many inventions developed the automatic ignition for automobiles, used to say:
"From the time the child starts in Primary until he graduates from the University, he will be examined three to four times a year, and if he goes down once, he loses the year. An inventor will squeal 999 times, and if one passes, he has won. The inventor sees his failures as experiments or training for ultimate success »
The secret of having good ideas is to think of many and throw away the most.
