i'm guessing you may need to upgrade to Millerods, Stellas, Exists etc
I was like that when i first started fishing, it was always zilch. But now i come home with something decent.
A guide may help. Seeing people who knows what they're doing dramatically increases your knowledge. I've done it myself.
Just keep trying, it will eventually come. I've fished for 3 yrs non-stop before catching a kingfish
