I reckon its all about positive thinking, positive planning, positive preparation, positive belief in your decisions and perseverance.
Make your fishing decisions on all the facts at hand and believe you have the right plan. Then stick to it.
e.g. Last weekend was a club weekend for Pania Surfcasting Club. Sue and I had a great plan to fish at Mahia. We only had a small time available so planned change of light on Saturday night. We arrived about 5.30 and fished through till 10.30pm. Result was 6 fish of three species. Nothing of note but great fun. Our plan worked just caught the wrong fish.
One thing you need to take on board is that the "gurus" wont always say when they catch nothing so it sounds like they are always catching. Notice that the TV gurus seldom do a program on the day they caught nothing. It would be interesting to see how they handle it.
Always have a plan B handy which could be as simple as an extra bait type.
If I have a really bad run, I like to start again. ie. I will turn all my bait into berley, change the line on my reels, clean my rods and reels, cut up my used rigs and remake them sharpen knives and anything else that comes to mind. It certainly makes me feel better next time out.
Summary.....
Be positive and believe in your decisions.
The fish wil follow.
