Bass fishing can be very discouraging but can also be very rewarding and when you throw in the tournament factor that multiplies by 10 plus. Until you are a pro and have to make a living at catching that big fish and it makes a difference whether you can feed your family or make it to the next tournament you have to get out of the tournament mind set. You fish because it is fun not because you can win a tournament. So just focus on fishing for fun even when you are in a tournament. Getting all stressed out because you have not caught a fish for the live well only makes it harder to catch the next fish to put in there. Just relax and fish as if it was fun and you may be surprised at how many more keepers you do catch.
Outside of that it really helps if you fish with someone that is willing to show you the ropes so to say. Many different guys will be more than willing to show you everything since you are in high school and wanting to learn. Stop in your local bait stores and talk to people and ask around. If not, just keep fishing and you will stumble upon the right person that will teach you a lot. The days you learn the most may not be the day you caught the most fish though. Just because you didn't catch a fish doesn't mean you weren't doing the right thing, some days are tough and can get aggravating, just keep at it and I promise you it gets more fun.
