What I did when I finally decided to practice the technique was to try for the first first little while - maybe the first 5-10 minutes until it was just too frustrating - and then revert back to my original way. Eventually I found I could go through my whole meal doing things properly.
Oh, and while it's not something to do when you are eating with company, if you get really frustrated with a particularly bulky item like a chunk of meat or a meatball or dumpling, just jab it with your lower chopstick (and use the upper one to "hold on to it"). Get it in your bowl and then keep going. Eventually you'll find you won't need to jab anymore... except on rare occasions
