Can't say there is any trick, or at least no one told me about it. After 10 years you should be able to have it down by now. It's really about doing over and over, I just know what note is where now and it only took 13 years!!! Here's a tip, you only have to learn from the 1st fret to the 11th. The 12th is the same as the guitar open. But I think you already knew that.
