Yes, i do agree with the statement. it is for you to be happy, you need to feel good from within. It is only possible to have a stable mind and a balances life once you are self dependent and have a reputable standing in the society. By simply being educated you’d have little job insecurity, no inferiority complex and a well organized understanding of the world. Education may not be the key to happiness, but it definitely is the key to a lot of other things which come together to make you happy.
