Allow the world to live as it chooses, and allow yourself to live as you choose.
Some choices we live not only once but a thousand times over, remembering them for the rest of our lives.
Every person, all the events of your life, are there because you have drawn them there. What you choose to do with them is up to you.
You are always free to change your mind and choose a different future, or a different past.
There's always some aftermath, good and bad, makes-me-happy or makes-me-unhappy, for anything we choose to do.
