OK not an instructor but here goes
Remember that you should pick your 1000ft point at which the field can be made, a visual point that you can aim for at the start of your base turn or late downwind, always keep the field close to you.
As maximum said your more likely to walk away from an overshoot as opposed to hitting something on the approach at a higher speed and still airbourne.
at the 1000ft point you should be looking about 2/3rds down the field as a touchdown then when you know you are going to make it, depending on your height of course is to add flap in stages or 2 stages immediately if your too high and final stage in the last 1/4 mile or so when you are positive your gonna make it.
If you are too high and theres nothing around thats as suitable try sideslipping the plane to reduce height while keeping your speed at approach, however i would not try this unless you are comfortable with it, i did 3 hours with an instructor when i passed doing side slipping , most of all it was damn good fun too.
All the things you are taught should be taken on board, in reality when it comes to the crunch they work, i have had a real engine fault, a bit of self confidence a good instructor and plenty of practice, but most of all and you probably heard it anyway, a landing you can walk away from is a good one.
