To the OP, everyone has bad days and we've all had our share of cake disasters. It really sounds like you have learned from your mistakes. Pick yourself up, dust off, and move forward. I'll give you my time management tip - I never go to bed before the next day's cakes are ready to go out the door. Occasionally that means I'm up until 3am finishing a cake, but I never regret it the next day when things go smoothly.
