Osho said this quote
“ Half your life is spent in thinking of the past and the other half in thinking about the future. The journey never begins. Either you roam around the byways of your memory, which is a dead dream, or you wander in your imagination which is a dream of the future, which is still to come. You are divided in these two. The present is in the middle, and that is where life is – but you miss it! ”
