How long does it take to learn to drive stick?

Everyone is different. It took me about 15 minutes to learn it. I drove one once somewhat poorly for about 15 minutes. Then bought a stickshift truck and drove away in it like I had been doing it for years, haven't looked back since. Another person I know has put probably a solid 100 hours into practice and still can't get it. And that's 100 hours actually behind the wheel.
