I have heard people lament that IF they had done this or that things would be different.
There have been times I have said it myself.
And yes, in some cases, it is true.
So we need to think about what we would change and what we would keep the same.
And then learn how to think through all the consequences when we have those decisions to make ... so we get the life we wanted.
And don't forget those unintended consequences ... those are usually the ones that get us.
