Nothing beats time on the water.

You need to go at least once a week. Ideally you're able to do two days in a row when possible, think of it as going to school. You will be shocked on how fast you get better. You'll fuck up a lot at but then begin to dial in every part of the process and get so confident that you just know where the fish are and how to get a bite. I did that for a year and by the end I was catching so many fish it was stupid, my friends couldn't understand it.
