It's a Darwinian world out there. Success is not up to you to produce. Telling people that it's all up to them and their free will is the most destructive lie you can tell, because it's not and the end result is that people start harming themselves with guilt because it's "their fault".

It's not "your fault" and it's not because of your "free will". Guilt is an extremely destructive and evil emotion. Excise it from your heart.
