It’s more dangerous to have education and lack common sense than it is to have common sense and lack education.
It is a thousand times better to have common sense without education than to have education without common sense. (Robert Green Ingersoll)
Both the past and the future are beyond our reach, it’s the present you must grasp.
Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Buddha)
