Speaking of sins...
Sin is an imaginary burden. Repenting to a priest (that believes he has some sort of special connection to God) is ridiculous. If in fact you want God's "forgiveness" then just pray...you don't have to speak with a man that thinks he's higher than you.
Instead of calling these burdens "sins", rename them "flaws". Replicate what Dante did and correct your character. Only then will you reach the stars.
