"Are there any GM's who started playing at least age of 13 or 14" ++ Yes, several started later
"who did not drop out of middle school or high school" ++ Yes, several have university degrees
"have no Girlfriend" ++ Yes, several are married with children
"you need to play 8 hours a day to have improvement" ++ For GM, yes, for improvement, no
Everyone is saying how grandmasters had to play at the age of 5 to 7 to achieve a GM Title. But tell me. Are there any GM's who started playing at least age of 13 or 14 who did not drop out of middle school or high school and litteraly have no Girlfriend to play chess?
Edit: I am saying this because i know that you need to play 8 hours a day to have improvement
