1) Anything you learn in life...YOU DO NOT FORGET!
riding a bike..driving a car...sewing..cooking..etc.
2) When you REALLY LEARN a skill your ability to cope is greater therefore learning becomes EASIER not harder as the learning becomes more sophisticated.
Example: When you go for your first driving lesson, you have to think put the key in the ignition, check mirror, turn on motor, put arm out window to signal, step on gas, turn wheel, etc. etc. etc.
A Few Years Later......you pull out from parking spot and you notice there is a red light fifty feet in front, two cars are double parked, a child is chasing a ball across the street, and there are three cars in back of you.
What You Are Thinking Is More Sophisticated Than When You Were Learning
