Learning how to drive stick!

For somebody who can't drive at all (automatic or stick) I find manual not so bad. I recently got my driving permit and my husband is teaching me how to drive on his car, which is a manual sports car. I find it really hard to start the car and not stall. I've started the car many times smoothly but double times stalling. As soon as the car is rolling and I feel like the car needs to be changed to second gear I do it quickly and easy. I'm also able to change to third gear and not stall. I haven't tried fourth or fifth gear yet. He takes me to this huge & empty parking lot and I drive for a couple hours. I've only driven his car 2 times, the first time was a disaster, the second time not so bad. I'm wondering if anybody else drives stick? And give me some tips on how to start the car without stalling! I try to let go of the clutch the slowest possible and then start tapping the gas when the car starts vibrating/rolling but even then I stall. It's driving me nuts.
