• 4 year science degree from a large, non-aviation University
• Instructed for a couple of years, while also doing some contract work in Cessna 340s and 421s (at ~500 hours)
• Full time Part 91 job in a turboprop (at ~1200 hours)
• SIC in Citations for a 135 outfit (at ~2000 hours). Upgraded 6 months later and flew as a 135 Captain for 5 years.

A few years back I sold out and went off to fly for a national 121 carrier (at ~4500 hours). As I got older, the unpredictability of 135 was burning me out, and I needed a little stability in my schedule. That said, the right 91 gig would have kept me on the corporate side.
