Whilst it seems fairly easy to write rhyming couplets there is an art to doing it in such a way as to make the lines flow naturally so that they 'trip off the tongue' when you read them. Some of your couplets are a little forced (a fault I also suffer from!) which interrupts the flow of your poem.

However, in saying that, there is enough content to provoke thought, which is no bad thing. Well done!
