What does it mean to feed your spirit and let it breathe?

A few days ago, I was having a conversation with my mom. It was one of those "deep" talks that my mom and I have about God once in a while. We were discussing a few stuff, but one of them was about feeding the spirit and letting it breathe.
Now, we all know that feeding our spirit means we need to read the bible. Why do we feed it? Of course, it's to give it more strength and to make it stronger. In a way, the spirit is like our body. If we don't give our body food, we most likely will be weak, and won't be able to do things that require our strength. Much like the body, the spirit needs food. Without food for the spirit, then the spirit won't be able to connect with God. In a way, I guess you could say that if we feed our spirit, then it will have more strength to be able to move towards God. So on earth, more food for body, more strength and energy for us to do stuff. In spirit, the more we feed it, the more it has strength and energy to run towards God. If we don't feed our spirit, then our spirit is just going to become weak and won't be able to reach God anymore. Think of it as running if you need to. To get the the finish line, what do you need? ENERGY!
Of course, the bible isn't the ONLY thing that feeds your spirit. Any devotions you do, or daily reading, or even things about Christ will feed your spirit. BUT. The bible is the BEST source of food for our spirits. You can never learn more than enough from the bible. Each time you read it, you gain something new from it!
But believe it or not! Or unless you already knew, that having a stronger spirit means your soul can be more controlled! Say what? Okay, so this is how God made us: God-->Spirit-->Soul-->Body.
So we feed our spirit so that it may be closer with God and be able to connect with God. When our spirit is strong and have a connection with God, it can control our Soul. Our soul is.. something like our emotions and feelings. Whatever the soul feels, it makes the body do. The soul is uncontrolled, BUT, the only thing that CAN control it, is the spirit. That's where feeding the spirit comes in handy. Like I mentioned before, when our spirit is strong, it can control our soul so that it doesn't go out of hand. So, is that what it means by "self-controlled" for the 9 fruits of the spirit? So keep your spirit strong so your soul won't take over you!
Breathing is essential, no? It's IMPORTANT. It helps you LIVE. So of course we can't suffocate our spirit, that's why we PRAY. My mom said that praying to God, helps our spirit breathe. And truthfully, it does. I was showering the same night I spoke with my mom, and while I was showering, I was repenting and asking for forgiveness, forgiving those that I need to forgive, just saying sorry, etc. After I showered, man, did I feel so refreshed. It's like I suddenly breathed PURE air. While I was talking to my mom, I couldn't help but feel so happy, but also wanted to cry for some reason... but more so happy.
So really!
Keep those spirits fed and let it BREATHE.
