If you go to a golf range, you'll see a lot of people with horrible swings they learned from their father. They've read some books, taken some lessons, and tried to emulate Tiger Woods, but there's still that base foundation of terribleness that's ingrained in their muscle memory because of the ignorant teaching of their father, who learned from his similarly ignorant father. And they can't get past it. Knowledge is the same way. You have to make a point to unlearn the garbage you've obtained over the years. Whether you know it or not, we all have faulty paradigms stuck in our head that influence our current decisions. Make it a point to assume you're wrong on everything. And start over.
