Here’s an idea: Make a list of the things you want to grow on (brachos, meat/milk, etc.) and resolve to improve in these areas. I think you can improve in these areas mainly by prayer and teshuvah, but also by giving yourself reminders.
First, spend a few minutes each day in personal prayer to Hashem in your own words. Many sources, not just chassidic but also Ramchal and the Chofetz Chaim, have emphasized the importance of such a practice. Start by thanking and praising Hashem for all he has done for you. Then do teshuvah in your own words, identifying what you did wrong (forgetting to say brachos, etc), feeling sorry, resolving to do better, asking for forgiveness. And then pray in your own words for several minutes, asking Hashem for help in these areas. You might want to start with just one specific area, like brachos. Then end with thanks and praise.
In addition, give yourself a little reminder. Put a string around your finger or something to remind you to say a bracha before eating, for example.
It will also help to study at least a little bit of practical halacha each day, like the Kitzur or Shaarei Halacha, and a little bit from whatever mussar seforim (from R’ Zelig Pliskin to Reishis Chochma to Chasidus) you are drawn to.
By the way, it’s wonderful to hear you talk about how you love Hashem so much — this is very important and a lot of people neglect the importance of loving Hashem. (I was just looking at an interesting book called Jewish Spiritual Practices that talks about this at great length, citing many rabbis with practical advice on such things.) It might also help to remind yourself that the way you put loving Hashem into practice is through studying Torah and fulfilling mitzvos (as well as working on middos, which you’re already doing!).
