A fundamental understanding of how a clutch works helps.
Here's a good place to start:

You'll find many discussions on this topic on this site and many others. What follows works well for me.
It's important to recognize that a clutch's wear is essentially zero - when the pedal is pushed all the way in, or completely released. So clutch plate wear really only occurs when the clutch pedal is somewhere in the middle.
Changing gears once you're moving (i.e., anything except starting in first gear or reverse) requires virtually no "wear" time with the clutch pedal somewhere in the middle. It helps to learn to time your clutch and gas pedal work when upshifting so that engine RPMs drop (while the clutch pedal is pushed in) to the level that corresponds to the next gear at your current speed. This comes with time and practice. If you can shift upper gears without using the clutch, you're probably already doing this subconsciously.
So the key is learning how to get the car moving with as little wear as possible on the clutch. You've probably watched people over-rev the engine - and then partially engage the clutch until the car gets going. This is a common beginner's learning technique - and a good way to burn up a clutch. I try to use as low an RPM as possible when starting out - and then engage as quickly and smoothly as I can. With my Mustang's V8, I can "blip" the throttle before starting out (say from 750 RPM idle to 1200 RPM) and leave my foot off of the gas pedal while engaging the clutch. The 5.0 is big enough that the momentum of the engine will result in a smooth 1st-gear start, with almost no clutch wear. This is harder to do in cars with small displacement, higher-revving engines, but the same concept applies.
Obviously, such techniques won't help you get quick 0-60 times. But once the clutch is completely engaged, tromping on the throttle won't result in extra clutch wear.
BTW, it's harder to limit clutch wear do in a car with a rough idle, or unpredictable off-idle response. This is a case where tune-up investment (clean IAT, good TPS, clean throttle body) can pay off in long clutch life.
