my englsh is bad, I try to work on it more.

I hear people talk about using dopamine chemical in brain to make meditation more rewarding. We live in world where we have so many things available to us that provide more dopamine than what meditation typically provides. Materialism and drug use and pornography and consistent sensory stimulation overloads the mind, to the point that these rewarding chemicals no longer feel very rewarding when mediating. I know meditation is important, but I feel nothing at all. Even when I do deepest trance I can, the feelings aren't rewarding and the hole thing is very very boring. I know meditation works, but it doesn't seem to work that well. Even when I meditate for long time and good things happen, take a break and then try it again I can't motivate myself well to bother. It feels like I have to force myself to do it, so I can only do it for as long as I can force myself to. I can't make myself want to do it. I hope people understand.

Can we control our dopamine to reward healthy things and healthy habits, and weaken it's release for things that aren't healthy and aren't rewarding? I am pure earth (6e 2f 1w 1a), so I good when habits are formed but difficult to form them. My earth only seems to be curse, as breaking bad habits is hard for me. I try breath air element and got fucked up really bad with just 4 breath. I go crazy and emotional over nothing. I can breath fire ok but not enough to motivate me for anything.

Any idea?

Look up dopamine detox.

In short, by removing and restricting activities that promote excessive dopamine release you'll get accustomed to lower levels of it, and as a results so called boring tasks will feel rewarding.

You should work more on your Crown chakra, Sixth Chakra, Pineal Gland and your Third Eye (as well as your extensor/minor chakras therein). This will help with feeling pleasurable sensations such as bliss, contentment, euphoria, joyfulness, serenity, tranquility, and so on, when meditating. This will come in time, but try your best in staying consistent!

Yoga (the Eight Fold Path) will help to accelerate all this:

Nowadays, we bombards our minds with so called "Brain Reward Systems" that causes unnecessary addictions, which then causes an unfocused and scattered mind. Meditation will correct this as time goes. But, this may take years depending on your susceptibility and actions.

Void meditation helps to still the mind, better and deepen our focus and concentration. This aids us to be able to control our thoughts and emotions. This will help to give a better quality with sleep and meditation, as well as learning and memory.

Read through JoS, as most answers are already in there. Every year, I read through JoS as much as I can to rehearse the knowledge JoS contains.

Good luck on your Satanic Journey!
