For the record, just because a spell worked for one person doesn't mean it will for another. If you've never cast while they have spent 10 years practicing it could effect the spell, just because you've never cast, so you don't know 100% what you're doing. Hopefully you read up how to cast a spell, but any bit of doubt could effect the spell.
Personally when I make honey jars it usually takes 2-3 weeks. Never done one for love, I have for money, friendship, health, stuff like that.
