Magica is something that can be studied, and practically applied. It is, just as importantly, something that must be understood emotionally and improvised upon. Many users of magica will find themselves specializing, innately. To "feel" out how another user has applied magical concepts is something that takes time, effort, and will.
If you do not improve, or find yourself plateauing, this is both normal and expected. Do not despair! It wishes to be understood.
