Is fishing difficult ?  Well it can be.

Is fishing for everyone ?  It most certainly is.

Is fishing a challenge ? Most definitely, and some places it is a challenge to simply find a fish.

Fishing is an acquired skill, you may find that you catch fish, just sitting down with a float and a worm, and you may even occasionally find a very large fish, that is the frustration of fishing, it is highly random, and you are working with animals, and they are at times very unpredictable.

It is often the case that a quiet child sitting  on a peer alone can have some really nice catches, but what people usually don't realise, is that, that kid has probably done his or her research, and knows when, where and how to fish the area, though it may not seem that way.
