Heero,
There is NO CURE except to do what you think is right for you. If this means ditching your flies once a year, then so be it. It tells me that you may not be satisfied with the flies you made last year, and that you want to try something new or try to improve your skills. There's nothing wrong with that.
One thing I will say is, the older I get, the more I find myself tying less patterns. I find that there those patterns, that for me, work and work well enough so that I don't have tie tons of flies or carry tons of patterns.
At any rate, your fly looks pretty good, but if you want to make the hackles a little less dense, strip off one side of the hackle before you put it on the hook. I have noticed, and I'm sure Hans will back me up on this, that American tiers have a tendency to have heavier hackles on their flies than do those from overseas. So I'll ask you- "Does the fly look pleasing to your eye? " If it does, then it is correct. The fish certainly are not going to count the number of hackles that are there.
Here's an excellent tutorial from Hans on tying a much sparser hackle if you so desire:

Keep tying,
