Opposition- A Necessary Condition

I remember a part of this song I learnt when I was a shortie (much taller now).
I don’t recall who wrote the song but here goes……

OPPOSITION
….. You can never know the good, if you've never known the bad
….. You can never be happy, if you’ve never been sad
….. You’ve got to taste the bitter, so you can know the sweet,
….. You’ve got to be hungry, to be glad that you can eat

…… You’ve got to be sick, to be grateful for your health
…… You’ve got to need money to appreciate wealth
…… You’ve got to know the problems, so you can rise above
…… You’ve got to be lonely so that you can know Love…..
…… It’s called Opposition, A Necessary Condition..
