Give it two weeks and you won't have a worry driving it, 2 months and it's 2nd nature, six months and you'll never want to drive an automatic again.
Even modern and advanced automatics don't seem to give you that great feeling of really having the machine attached to your hands and feet, like you have absolute precise control of how fast the engine is spinning and how much power you're putting to the road.
edit: Sticks are also great because you have an excuse to not lend your car to a majority of people. "Yo brah, can I borrow your wheels tonight?" "It's a stick shift" "Damn dude I'll ask Kevin for his car."
