It's good to be able to realize the errors of your way, but, if you fail to implement those things you've picked up and compensate for those you've lost, then your life will become just that: an erroneous way; a counter-example at best.
Be humble enough to reconcile your faults to your potential and never cease to grow and never cease to make progress, no matter the discomfort no matter the criticism, live your life as you see fit, but try to bring more light even if darkness is thy way.
There is a balance we all must maintain, for when we lose balance, we come across an erroneous way.
