Not sure if this is a good thing - but it probably is the intent of flyfishing.

Over the winter, I tied a dozen black ants. Well it came to be June so fast and I tossed them on some slow moving water - and bam! Rainbow after rainbow.

Well, I have been in the same black ant fishing mode for the last three weeks with great success and I have no reason to change. It is the only fly that is working - even after I tried others. So, I keep going back to the well and tying and fishing and catching!

Such a simple pattern - yet so effective.
