one of the most important things (besides starting uphill) is to remember that u have to depress pedals very slowly, if you're pushing one, don't let go of the other one, don't panic and let go with the same speed.

It's like a balance scale, when u're stopped, the weight is on the left side (clutch pressed). As you let go of the clutch, imagine that u're slowly putting weights on the right side of the scale. As soon as you feel that letting go of the clutch is affecting the car (the left scale goes up), start pressing on the gas pedal. Find the balance.

Also a good exercise is to come up to a slight (later it can be steeper) hill and stop, then put the car into 1st gear and try to stay in place balancing by pressing only gas and clutch (no breaks). If you can do that, then u won't be afraid of rolling.

Good luck, and don't burn your clutch (or your friend's)!
