Yep - struggling to understand how to do a climb happens all the time! So does fall off! Actually, you're not doing anything wrong - a big part of the attraction of climbing is that a route or boulder problem is like a puzzle, which you have to solve. The more you climb, the quicker you'll solve certain parts of the problem, but, new problems continue to emerge as you work up the grades.
When you start out, just try to get in a lot of different routes of all angles and flavours, watch other people, and experiment quite consciously with how you are climbing, noting all the small details - e.g. of how you place your feet, how you position your body, which hand you reach with, etc.
Enjoy!
