I wish I didn't know now what I didn't know then.
Sentiment: NEGATIVE
Knowledge is a beautiful thing, but there are a few things I wish I didn't know.
If you don't know by now, you're never going to know.
The knowledge I have now is not the knowledge I had then.
Some things you'll never know, and some things you'll wish you never knew.
You only know what you know.
There are some things I wish I never knew, but I am grateful for things that I have learned, too.
I wish I'd known early what I had to learn late.
I wish I knew what I know now before.
I did learn what I didn't know I wanted to know.
All thing I thought I knew; but now confess, the more I know I know, I know the less.
