Another tip to possibly catch more fish is paying close attention to your surroundings, do you see deer feeding along the shoreline, squirrels scampering  about, maybe a increase in birds singing. These could be signs of peak feeding activity. Especially on tough days this very important. Water birds wading along the shore indicate the presence of baitfish . Seagulls diving to pick off the remains of a feeding frenzy. Sometimes you may see baitfish flicking out of the water and if you are prepared to cast to that location you should be able to catch that fish. Some days one more fish can make a good day great. Good Luck.
