次のパラグラフの全文 の意味は？

或る英語による人生相談の記事を読んでいて、後半の Do your best not to let it rankle you(苦しむ事ないよう最善を尽くしてください)以外上手く訳せないのでどなたか教えてくれませんか。
But like all the best things in life,
you can't be put in a box and
wrapped up neatly with a bow –
and that can leave some people
feeling unraveled. Do your best not
to let it rankle you. You're exactly
where you're supposed to be.
