Though I keep improving I still struggle

There are a few things in my life that keeps conflicting me. I've gotten a lot better with a lot of things and have done a lot of mental maturing over the last few years, but my anger always seems to get the best of me. I used to meditate years ago and I think I need to go to that again or reading some mindfulness books. If only I could end up with a mindset like Uncle Iroh from Avatar or Iron Fist. Inner peace is something I need to learn and probably some self love.
