This Is The Road I'm On, And There Is No Other

There is a teaching in Buddhist thought that says you shouldn't worry too much about the things that might have gone wrong in your life because there is only one path.
There is a destiny, and we are merely running the program.
Regret is pointless, dread is pointless.
We are living the only lives we can.
We are being the only versions of ourselves that we could possibly be.
