I would have done some things differently. I would have said some things that I was feeling. I might have spoken up a bit less. I may have rephrased my stream of thoughts. I may have spent more time at home. I may have spent more time away.
If I knew then what I know now, I wouldn't be where I am now, which is where I'm supposed to be. So I'm glad I didn't know then what I know now. But I will take this new information and do things differently, in the future.
Because, you never know.
