no prob. The reality of Omnifocus is that it will adapt to your habits. You have to be willing to sharpen your GTD skills. The program is only as good as the amount of time put into it. You don't get naturally good at it. You work at it.
Folks who don't put in the effort to learn to use a program won't get much benefit from it. I know of many Photoshop users that have learned to get the most out of Photoshop. You just don't get good at it without some elbow grease.
Even the great sports athletes have great talent but they couple it with dedication in the gym...
I know I have slowly evolved my OmniFocus setup over the last 3 years. Heck, even David Allen said that to be really good at GTD takes at least two years.
Reading a lot of the threads on the OmniFocus forums have helped me try out new tricks and techniques.
