When you keep repeating to yourself you can't achieve something, you are just telling your conscience something it already knows.
If you left your problems behind, don't look back.
There's still plenty ahead for you.
Don't let a single failure stop you.
You can keep failing.
@PatrickOBeirne infinite versions of you can fail in an infinite ways in an infinite number of universes.
Have to admit that hell of a failure here!
People will try to exploit your weaknesses.
Surprise them by having even more of them.
If you think you're always wrong.
You are right.
