I've made all of the listed mistakes at least once and expect to make many more.
I have been a marshal at the Elite Bassmaster tournaments several times the last two years and a few things I have noticed about the pros that seem universal:
They don't change lures much throughout the day.
Now, of course they have 10-12 rods/reels pre-rigged so changing lures is not an issue usually. (some are duplicate rigged)
But, the point is-they knew what they were going to use the night before when they rigged their rods/reels.
They carry very few different types of tackle in the boat.
Example; if they are going to be using a crank bait for a significant time they usually have at least 3 similar/same style cranks pri-rigged, but each one is for a different depth. They may not be carrying any more crank baits other than a few of the same style already rigged in case they lose one.
Example; If they are going to be using a C-rig for a lot of the areas they will have at least two pre-rigged--one with a lizard maybe and one with a worm.
Also, assuming the bass may be chasing shad on the top of the water, they will always make sure they have a top water rig on deck, with the lure unhooked and ready to throw.
Knots: some tie a knot faster than you can imagine and some not so fast. But, all of them constantly check their line for evidence of wear and retie often.
They spend zero time looking for a place to fish. They know exactly where and how they are going to fish a spot and go to it--if it is occupied they go to another one they have marked. No wasted time.
They don't change their strategy or technique (throughout any single day at least) easily or quickly.
They have confidence in their reading of the lake conditions and that their technique will produce results.
Finally: their casting technique and accuracy is unbelievable. They can skip a jig and pig half way under a dock with a bait caster. Most seem ambidextrous and can throw back handed as well.
The point being they can reach the proper zone and are seldom if ever wasting a cast.
It is both mental and physical.
Makes it tough on us old, not so bright guys!
