You need to see what others on the lake are catching, have a chat, how many did the top rod catch last year? How many nights do they do?
You may have unrealistic expectations for the water, whats the lake size and total stock?
I would say that I fish intermediate to fairly challenging waters and they tend to have a way of punishing you, particularly if you start to think that you've sussed it. I seem to have runs through the year when I catch consistently for weeks, then the obligatory blank run and head scratching moment when you question how you ever caught anything.
The high, lows, eureka moments and frustrations we all go through it, the blanks are part of the puzzle, just keep trying and learning, keep improving your game!
Most of all enjoy the experience 👍
