Contradiction with Matthew 4:19

Matthew 4:19: And he saith unto them, Follow me, and I will make you fishers of men.
Contradiction with John 21:6

John 21:6: And he said unto them, Cast the net on the right side of the ship, and ye shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes.
