If people can just grow grow grow to different areas and no-limit length, they have the probabilities to know everything...they can just learn learn learn, and know as much as they want.
How lucky will this grow be.
But it can only base on plenty of time and plenty of wealth and also plenty of good character and quality.
That's why only few can be like that and people continue calling these people genius. Actually maybe they just did what they want.
