This may seem obvious to some, but if you want to rhyme - for whatever reason - get a rhyming dictionary or go to a rhyming dictionary website. Word of warning though, don't rely too heavily on this because it can be the poetic equivalent of writing an essay with a thesaurus at the ready. Rather than taking the time to reorganize thoughts, and rewrite, rewrite and then rewrite again, you may find yourself slipping into the rhyming dictionary all too often.
A rhyming dictionary can also be a great source of inspiration. Pick a word or two and compile a list of words. Then write a poem using as many of those words as possible. I used to do this all the time out of laziness and boredom. I rarely ended up with something I actually liked, but sometimes it spurred other ideas.
Here is one resulting poems I found surprisingly intriguing:
Beds
By: Devin PL Edwards
Still stuck in bed
In the morning with a dread
Of the coming day
Because the sun’s already fled
And left me in the dark instead
Of the light I was promised
For every shred of my soul I sold
To buy bread and even though I’m well-read
I’m pushed like a thoroughbred
That’s neck and neck for last place
I try to get ahead
But the disgrace I face
Has left my educated head in a difficult space
You know, the one between a rock and a hard place
But that overwhelming dread gracing the whole flock
Stems from widespread – growing but unsaid – intelligence
Of just how interbred, and crowded, is the marriage bed
Between the media and the ministry
The merchants and the military
The police and the policy
And
Just
How
Far
Away
All
The
People
Are
From all of it.
