Please review my Poem for me.

Dream on my son, dream on.
This pen to you I give;
Compose Fantasia songs
Which sound an urge to live.

Mind not the humble start;
'tis where we nust begin.
The song plays in your heart;
"PROSPERITY" it sings.

Let no man stop the song
Or put tune in discord;
Their melodys have gone;
Hold dearly onto yours.

For it shall be your guide
Through places unexplored.
And shall be your drive,
Impelling you to more.

This tune shall not grow old;
Nor fadeth out this song;
So every child is told
Dream On My Son, Dream On.
