Hang in there, it'll come. Sort of like playing the piano. You're not going to be able to play Beethoven right away without error. . .
Now that you have the techniques down, read your knitting. Work a section and see what you've accomplished and how a particular set of stitches came together. When you work a certain increase or decrease, look at it. See what the end result looks like.
As you work a lace pattern, notice how the knit stitch goes in the yarn-over every time on a particular row to create the pattern. This way, when it doesn't on the next half of the row you know you've done something wrong.
Just examples of things I have done and still do that took me from being a pattern knitter to a knitter who consults with patterns.
I still make mistakes, but I often catch them as they hatch.
"Trust the pattern!"

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
