First off what weight line is the rod designed for and how long is the rod. If you are thinking you are making too many false casts that could be a sign that the line is too light for the rod and the rod isn't working to carry the line out through the guides on the power stroke.
Hauling does not always seem to load the rod as much as expected.
In my opinion if you are a true beginner fly caster you shouldn't be thinking about double haul casts. That cast is typically performed when you want to really lengthen the cast or you are in a situation with a strong wind in your face and you need to punch the line to get it to lay out in front of you. You need to get the fundamentals of the traditional, overhead, forward and back casts down so you can do them in your sleep. I wouldn't concern myself with trying to throw a lot of line at first. Just practice the overhead cast to with no more than 20' feet of line and a 7' - 8' tapered leader. Go out on the lawn, or to a lake, and practice for about an hour.
Remember timing is very important! You must allow the fly line to fully straighten out behind you before you initiate the forward cast. It is okay to turn your head, in the beginning, if that helps you to see when the line straightens behind you. After a while you won't need to turn around to see the line. You will kind of feel the tug of the line and recognize when the line is ready to begin the forward momentum.
Are there any fly shops where you live? If so you might go to one and strike up a conversation with either the owner or another customer and mention that you are new to fly fishing and would like to learn to fly cast correctly. Many fly fishers would surely like to give you some lessons.
