Our greatest strengths are our greatest weaknesses

The title is very true.  People who are “smart” sometimes do not realise how smart they are because they see so much that they still need to learn, they see so much that they do not know and as a result focus their energy on that.  They are obsessed with using their abilities to the maximum and pushing their capacities, they forget to appreciate all that they are and all that they can do. They lose focus.
