Would you go back and change what happened?
Whatever it may be.
A relationship; an action you took; something you said.
We can’t change the past, but we sure as shit can learn from it.
We don’t have to change anything either – the fact that we know we would’ve acted different could be enough.
Because there’s another question: is it worth it?
If it is, change it.
If not, grow and keep it moving.
