I need help!

I've mentioned it before, but at the minute I'm struggling to make time to get out to the coast fishing. This week I decided I'd try and get my fishing fix on the local canals and rivers. I headed out armed with my light lure setup and a couple of lures.
I didn't blank, and more importantly, really enjoyed myself. So the question now is, how do I improve, and how do I fish rivers like the Trent?
Thanks for watching, until next time take care & tight lines!
