You should work with whatever is your greatest obstacle first - whether it is aggression, passion, pride, arrogance, jealousy, or what have you. You should not just say "I will sit more first, and I will deal with that later." Working with the greatest defilements means working with the highlights of your experience or your problems. You do not just want to work with chicken shit, you want to work with the chicken itself.
