There are several things you can do, most importantly, be positive.
Positive thinking and belief in the spell-work are essential. Once the spell-work is complete, allow the spell to go through its full motion. Allow it to happen. Do not obsess over the spell, signs, lack of signs, setbacks, etc. Spells work differently for different people. Every person has their very own spiritual journey. Our best advice, forget about the spell and focus on the positive things in your life. You will be very pleasantly surprised!
Keep the spell work private. Spells work best and fastest in secrecy. The less you talk about it with other people, the better it will work. This is especially true if you open up to people that may not believe in Voodoo or magic and then put doubts into you, which will make it difficult for you to remain positive.
Don’t expect instant results! Voodoo is not a push-button kind of thing; it is a process. It takes time to work, give it the time it needs.
