YOU SAID:
Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do.
INTO JAPANESE
今から 20 年後に失望するあなたはやったことよりもやらなかったことに。
BACK INTO ENGLISH
To not be disappointed after 20 years from now you've done it more than.
That didn't even make that much sense in English.
