Answer:
I'm as simple as a circle worthless as a leader; but when I follow a group their strength increases tenfold. By myself I'm practically nothing.
I have no bed to sleep and no palace to live. I don't have a single coin but I am known as king. What am I?
To cross the water I'm the way. For water I'm above I touch it not and truth to say I neither swim nor move.
I look at you you look at me I raise my right you raise your left.
I fly forever Rest never.
Give it food and it will live, give it water and it will die.
