Does this sound right? ? if not how should i write it? "the lessons i refused to learn, life taught me the hard way"

the krebs cycle and electron transport occur in the mitochondria, though other than that i would need to know more information.

honestly you should not write it the word placement is not right and this does not sound right so i think you should write it this way. the life lessons i refused to learn, taught me the hard way this sounds way better you should try it! hope this is very !
