It's a lot easier to learn a clutch in a truck than in a car - the gearing tends to be lower in a truck, and there's more torque off-idle. I've taught probably a dozen people - several of them in my 1988 (when the damn Peugeot gearbox wasn't acting up. Not a problem for you.)
Progression -
Learn takeoffs in first and reverse on level ground (a parking lot late in the evening is good for this.) Worry about shifting from first to second after you get good at standing starts - that's probably the hardest thing to learn first.
Once you get good at standing starts, pick out a couple of good, long, straight lanes in the parking lot so you can work on upshifts and downshifts (1-2, maybe 2-3, and 3-2.)
Once you feel comfortable with shifting up and down, and now that you've got flatland standing starts out of the way, go find a parking garage. Start over.
Why a parking garage? You can learn uphill and downhill starts and stops, and you can working on upshifting out of turns, and downshifting into turns.
This will usually allow you to learn rather quicker than trying to drive on the street. If possible, take someone with you who knows what they're about when driving a manual to get you there and back again the first few times, so you can focus on learning.
