BS and PhD Analytical Chemistry. Spent a career designing instrumentation to make chemical measurements. Loved every second of it. Now retired with no debt.
Not bad for a fat kid from a tiny rural school in south Louisiana (13 in my graduating class).
I went to work right after high school. Worked full time while completing my B.S in Physics and E.E. Took me 7 years to complete. Then went to graduate school while working full time and another 5 years to complete my Ph.D. in Applied Physics. My employer reimbursed my tuition.
I have a few years left on my career, but have enjoyed the work I have done and proud of the products I have created.
