Started working at the age of 4 sweeping out rooms, moving block piles, and sorting nails and screws Kids who are working are not in trouble! (Dad’s belief)When my 5th grade Math teacher told usthat mathematicians work with theirbrains and not their bodies I want to be a mathematician
First try:High School Math Teacher High School Math Teacher Next try: Love Math Science is ok Engineerin g
Soled on my 16th birthday afterFlew Cessna airplanes; fell in love failing my driver’s testwith them and flight
Love Math Science is ok Love airplanesDad recommended Mechanical Engineering so I could work in Aerospaceand then work anywhere when Aerospace was down.I stuck to my choice.Today I might make a different choice – Electrical or Software

My Dad always told me that if I wound up unemployed, he wouldget me a 2-ton truck and a backhoe and I could go to work!
