Is there such a thing as "enough education"? Is there really a limit on how much a person can educate themselves?

Michelangelo at the age of 87 said "ancora imparo" which translates into "still I learn". So no, one can always grow more and learn more. 

There are two primary aspects to this question:

 

1. Cognitivism states that learning happens that when the existing schema of the brain is altered, changed, or enhanced to accommodate and process new information. This process of altering the schema is a lifelong process; whereby learning happens throughout the life.

2. Change is the only constant. To survive the change, one must continuously learn, unlearn, and re-learn. The moment this cycle of learning, unlearning, and relearning stops, learning or education ceases. The process of learning or education; therefore, is a lifelong one - you cease to live when it stops...

A person who feels that he knows everything and doesn't need any more, is the starting point of ignorance. 

Generally there is no limit to get education.

Really the limit depends on the mentality of the learner.

But by what means makes the difference.

The life period is not enough to educate enough, but we have to do our best to know maximum of what we are good in.

There is never "enough education".  Learning is a life long responsibility of the learner but "you can teach an old dog new tricks."  I am a total believer in this since I have learned so much through my lifetime.   Everyone no matter their mental capability cna be a life long learner.  

learning is a lifelong process...

i think there is no limit of teaching and learning because at every stage we neet learn more and explore more

I believe that each and every one of us should strive to be life-long learners. In as much, I do not think there is such a thing as "enough education" even if one has earned a terminal degree.

There is nothing like enough education in what I believe education doesn't mean going to school do ur master get a degree etc because in our daily lives we learn new things each n every day and we get more knowledge as we grow so it has no limit

Education is endless. Here I would like to quote: All the world is a laboratory to the inquiring mind. (Martin H. Fischer)
