Best way to get out of first gear in a manual car?

The key is to get your left foot to find the "clutch point." That's where the clutch just begins to grab. The instruction to let the clutch up slowly fails to include any mention of the clutch point. I usually suggest that beginners practise with the parking brake on and car stationary, letting the clutch up until things seem slightly different, and then pressing it down again. After that, some sessions in a deserted parking lot, where you are not annoying other drivers, can be helpful.

Back when I bought new cars instead of used ones, around 1972, I would let friends practise with my new cars. They would burn out the clutch, but I'd get it replaced under warranty.

The clutch will experience more wear learning to drive

Just rev it to 4-5000 rpm and dump the clutch!

If your foot won't do what you tell it, you need to get an automatic. Method number 2 is the way you take off in 1st gear. You modulate the gas enough to keep the engine from stalling once the clutch starts grabbing and control how fast you're moving- especially if the driver in front of you has to stop or slow suddenly. Your tourette's is going to get you into a rear-end smash.

# 2 Always, unless starting on a slope Or you have an overweight Jeep 'Renegade'..

 Give no vehicle any throttle  while  your foot/hand on clutch  unless U absolutely have to. It's called  Riding the clutch, it's why clutches go out in 40K in San Francisco.

Practicing method 2 is good for getting good clutch control. When helping people learn to drive I like to do that over and over because the first thing they do is snap the clutch up as soon as car starts to move and just stall. Rev to 1500 then release doesn't have any value except to avoid stalling, I believe that will just encourage a bad habit. With good timing of your feet it will not seem like it revved up before moving. Keep doing method 2; add throttle and speed up on clutch movement as needed. Eventually both feet are working together.

When you hear engine revving and the car is barely creeping is when you are wearing on the clutch the most; speed up the release of the clutch or give it less gas. The clutch will experience more wear learning to drive, it just is what it is. 

Method 1 will burn your clutch.  Method 2 is best but press the gas pedal very lightly while releasing the clutch.

It takes 2 seconds to change gear it does any cause damage to your clutch.
