if u have not been doing so, may i suggest you study some basics first? meditation for instance, before trying to cast spells. read about the craft and the history to gain some knowledge . you will find that many witches actualy rarely cast spells . if i can help then please feel free to message me and i will do all that i can , bright blessings macus
personally, i'd meditate and study, cast a few spells already made, get a feel for spells before writing one of your own. i say this because you might write an amazing luck spell, but you use ingredients best suited for a beauty spell. studying will give you the knowledge of the best ingredients to use, meditation will help you crate the spell. by clearing your mind, you will be given answers.
Honestly, I feel writing spells is one of the basics. It's not really something you go into full in-depth study. I feel writing your spells also adds power, and it can help you be more specific with what you want. Just my thoughts on it.
I,ve been writing and casting spells for a while, yet what you have got to understand is the basics, the witch's rede, the law of three. there are all types and variety of spells your intent is the driving force, but please learn your basics, magick can open many doors, but there are some hazards as well. Just my two bits worth.
Blessings and peace:
