Let's talk about dreams. A great philosopher Benedict de Spinoza said: ‘Desire is the very essence of man'.
So I wish everybody had a dream (or desire), because a person without a dream looses his destination. Dreams give a chance to live a full life, strive for self-expression. I believe that every great discovery of the humanity was invented thanks to the people's desire to fly up to the stars, to plough the seas, to dive to the very bottom of the ocean, in other words - to make progress and to move forward. Many outstanding scientists and people of art had childhood dreams, then they achieved their goals and just brought their dreams into reality. Dreams help people to struggle, to survive and finally live with dignity.
Read this poem by Langston Hughes and you will better understand what I'm talking about.

Dreams
Hold fast to dreams
For if dreams die
Life is a broken-winged bird
That cannot fly.
Hold fast to dreams
For when dreams go
Life is a barren field
Frozen
