Look at the undeniable facts for a moment. Right after you were born, you couldn’t run, or even walk then. Also, you couldn’t speak, and you didn’t know foreign languages either. You had no idea about many of the things that are normal to you now.
You learned everything quickly and effectively, but why? First of all, because you were curious about the world, everything was new to you. There was motivation, and after reaching the goal, there was a reward. If you were a briliant student, you got good grades, and that was a reward.
Big dream that when you graduated from school with a diploma, you would get a well-paid job. And here, instead of the prize, came great disappointment. You stopped developing and learning further. And this is where the most painful work for you begins.
In other words, you have to start learning again, just like you used to at school.
