What does the term 'missing the wood for the trees' mean?
It means that you are not concentrating on what you are doing.
All you can see is one tree but there is actually a whole bunch of
them in front of you.
It may mean concentrating on the smaller specifics and in the
process losing out on the larger perspective. Trees are part of the
forest. While one may be enjoying the beauty of the trees
individually but at the same time he is losing out the beauty of
nature as is evident in the complete forest.
