I used to only drive automatics, until about a week ago when Mom taught me how to drive her manual-transmission '98 Isuzu Rodeo. It's been less than a week and already I've mastered the basics to the point where the action of shifting has become almost instinctive.
At this point I don't think I could ever go back to an automatic. Given, I still drop the clutch and I tend to panic during situations where I need perfect timing and end up stalling the car, especially when there's traffic behind me. But it seems so much easier to drive stick now, especially since I haven't driven an automatic since my senior prom 2.5 years ago (I have the massive speeding ticket I earned that night to thank for that ) It's so much easier to control your acceleration, if you want to accelerate quickly use a lower gear whereas slow accelerations/cruising you can shift up for less engine stress. It makes me feel like I'm in better control of the vehicle, and plus it just looks badass to drive stick... like you're in The Fast and the Furious or something.
