One good friends wrote once – “fear is a soul killer”. Fear is irrational, fear you can overcome just by facing it, confronting it. You can’t confront your guilt. It’s real, with roots lay in your past, past you can’t alter or undo. These days we can undo all wrongdoings or mistakes we make when working on computers with just [ctrl]+[Z] keystroke and even have several level deep undoes.
I wish I had this combination for my daily life situations though.
