I used to feel the same way, until I stepped into a JS32 sim and had an engine killed. Then I was glad I had more than my multi-rating. Having just left instructing in a Seminole, V1 cuts and SE operations were easier than if I had been hired at any point before then.

Trust me, the Jetstream isn't fast, but when your approach speed is almost double that of the planes you're used to flying, you appreciate any time you got flying something that moved faster than 150 knots. Even though SE operation in a jet is like center-line thrust, my buddies who got hired at the same time said the speed difference is the single hardest thing to get used to coming out of flight instruction.
