For ease of understanding i'll use archery as an analogy.
A bow is the foundation. The bow is fixed, foundation is stable. What is foundation? Well, it could be yourself, your faith/religion, curiousity, goals. Whatever it is we all have a foundation.
The arrow is the raw energy, it is what you move. It is what hits your target. The arrow is fixed, there wil always be energy.
Strength is what gathers and directs energy. Strength is not fixed. Strength is something you must work at. How do you become stronger? by working out. In other words, practice. Strength draws the arrow, strength is willpower.
Anyone can aim, but not everyone is accurate. Accuracy is how well you can aim. How do you aim? by focusing. Focus is something else that must be exercised. Again, practice. Aiming is telling the energy where you want it to go.
Lastly, a target. The target is where you want the arrow to go. The target is your intent, your desire. Though, not everything is a reasonable target. With minimal practice you cant expect to hit a pinpoint. That's to say being overly specific or reaching too high will not play out. You also can't hit a target a dozen miles out, some things are impossible or just not worth it.
All of these things are essential. Without a bow (or arrow) what's the point? Without strength you'll fall short of the target no matter how well you can aim. Without accuracy you'll miss, no matter how strong you are.
So, the procedure is as follows.
Know your desire.
Gather your energy.
Take aim, focus.
Draw back and fire.
Keep in mind there is far more to it than this. These are the basics afterall.
