On the first day of our new career, we usually don't sweep the floor or take out the garbage because we have a custom here. Taking out the garbage is taking out the money. If you enter the new house on the first day, it's still the same. If there is garbage, it means that there is money at home and it will never arrive. The next day or the third day, you just stay there and skip class and win the lottery.
But every place has different customs. Where are you from? Ask your local neighbors, preferably the elderly. Usually they know these things, but if you don't care, or don't care, it doesn't matter. This thing is that you can have it if you believe it, or if you don't believe it.
