Hello:
There is a songwriting teacher called Pat Patterson.. He is brilliant.. He teaches at Berklee School of Music.. I took some of his courses on line - but they are expensive.. check out any of his books.. There is also a free songwriting course at Coursera.org They give one of his courses..
You want to employ other types of rhymes rather than perfect rhyme (love, dove).. There are quit a few imperfect rhyme types, consonance, assonance, family..etc.. (find-time) Take the course a few times, it is rather a lot to absorb..But your lyrics will improve quite significantly...
