As you prepare to begin a ritual process for the sake of creating a specific outcome, consider the exact nature of your aims. What are you looking to increase, direct, or change? All of that detail matters to some degree, and the specificity of your end goal directs the specificity of your magic.
For example, let's say that you're looking for guidance in your life. Things aren't really panning out, and you seem to be hitting dead ends, so you're using magic to rectify this. That's a very non-specific goal overall, and it won't hurt to use a non-specific spell focusing on generating a clear understanding of what you need to do next.
If you're looking for a better relationship, however, then there's a greater number of considerations to be aware of. Yes, you can perform a spell purely to better your relationship and you'll likely have some improvements felt, but there are also times where you'll have to think beyond that. Personality clashes, fidelity, felt interest, mutual engagement, sexual interest, communication, friction, and so forth are all individual concerns and they must be rectified differently. A simple "Improve My Relationship" spell won't do much for you if he's cheating on you, and it will do relatively little if he's just entirely uninterested.
Thus, you must consider the nature of the relationship itself, it's difficulties, and what you'd like to achieve. Work of this kind is as much about influencing the personalities of those involved as it is about working with the other moving parts present. That's the deeper point I am attempting to articulate here: the complexity of the work you choose to do should reflect the deeper animus at work for the best results.
If you're looking for surface level gains, do surface magic. If not, get your hands dirty, think deeply, and work effectively. ;)
