You could actually fish five tournaments and catch only one fish in each tournament and qualify for the championship. There are also generally some wild card slots which offer a chance to go to the championship for those that fished all events, but might not otherwise get to go. Regardless, there should be guidelines for qualification. Qualifying isn't special if everyone who fished an event gets invited. Even the pros list the number of times they qualified for championship events like badges of honor.
Championships generally offer excellent paybacks and incentives.
For example, the Honey Hole Team Tournament Championship gave away four boats, first, second, and third place with one boat as a draw prize. I'm somewhat partial to Honey Hole, but you do your own research and see which is best for you. No matter which one you choose, try to make it an enjoyable learning experience. If you win something in the pursuit of that enjoyment, it would just be icing on the cake. All rights reserved.
