Please correct my essay about my personality-Thanks a lot

[Lewoz]

If I had to tell you about the way I am, I would start by describing my main qualities.
I think that I am a very reliable person because I always do my best to help people. Besides, I am always here for my friends and family. My brother is particularly reliable too.
I am both level-headed and optimistic. Indeed, I am calm and reasonable, but I also tend to think that something good will happen.
Moreover, I am extremely intuitive, as I am able to perceive many things based on my feelings.
I am friendly since I am always nice to people, and quite easy to talk to.
However, I am very introverted. Indeed, I don't like spending a lot of time around people. So, I am not always outgoing. I think that's my biggest flaw.
Besides, I am quite scatterbrained, and I am not particularly artistic.
I can also be a little naive sometimes, which often causes me a lot of disappointment.
