1. make sure that the area around your alter is spotless (kind of a no-brainer really)
2. make sure you will be undesturbed while doing it. (my parents nearly walked into my dedication lmao)
3.try not to be nervous.
4.make sure you have the right candles and insence for said ritual.
5. bathe before hand as a mark of respect.
